Gem Diamonds finds two large rocks at flagship mine in Lesotho

These are the two stones unearthed at the Letšeng mine in Lesotho: a high-quality 104.73 carat, D-co

Africa focused Gem Diamonds has discovered two diamonds bigger than 100 carats at its Letšeng mine in Lesotho, which should help the company boost revenue and investors confidence.

The two massive diamonds are a 151.52-carat Type I yellow rock and a high quality 104.73-carat, D colour Type IIa stone, the London-based miner said in a statement. "The last time Gem Diamonds had made a significant discovery at its Letšeng mine before April this year was in 2015." The findings come on the heels of other key discoveries at the mine. In April, the company announced the recovery of a 114 carat diamond and last month it found one of the highest quality diamonds to come out of the Letšeng mine an 80 carat, D colour Type II diamond.

The last time Gem Diamonds had found a significant diamond in Lesotho was in 2015, when it unearthed an “exceptional” 357 carat rock, later sold for $19.3 million. Investors reacted positively to the news, with the stock was trading at 1.64% higher at 93 pence around 2:00PM GMT.

Since acquiring Letšeng in 2006, the company has found four of the 20 largest white gem quality diamonds ever recovered, which makes of the Lesotho mine the world’s highest dollar per carat kimberlite diamond operation. At an average elevation of 3,100 metres above sea level, Letšeng is also one of the world’s highest diamond mines.

Kimberley Diamonds closes its last mine

Kimberley Diamonds

Controversial Australia-based miner Kimberley Diamonds has put its last remaining diamond mine into administration after it failed to secure fresh funding.

Kimberley, which avoided an estimated $40 million clean-up bill after it walked away from its Ellendale mine in Western Australia’s north, shut its Lerala operation in Botswana last week and placed the subsidiary responsible for the project into administration.

Kimberley said in a statement on its website that its subsidiary Lerala Diamond Mines had “no choice” but to place itself into administration after the parent company was unable to strike a new financing deal.

It had earlier stopped day to day operations at Lerala pending an overhaul of the mine’s diamond processing plant. “The successful completion of this performance improvement plant required further funds to be provided by investors and despite considerable progress being made on implementing these improvements, all of the required funds have not been forthcoming,” Kimberley said. “Kimberley has been in discussions with investors regarding further funds for some time, however to date no agreement for further and sufficient funding has been reached and KDL has been forced to cease providing financial support to Lerala.” But the collapse of Lerala won’t kill off the parent. Kimberley said it remained in discussions with investors for further funding and was “exploring corporate restructuring options”.

Kimberley delisted from the ASX earlier this year after a chequered history. The stock enjoyed a charmed run early on, surging from 11c in 2012 to $1.30 in 2013, but fell spectacularly in 2014 when it revealed it had failed to secure a price increase from global jeweller Tiffany & Co that it had already factored into its profit forecasts. Its shares never recovered, and last traded at just 0.7c prior to its delisting.

The company, chaired by former stockbroker Alexandre Alexander, also came under fire for its handling of the closure of Ellendale. The liquidators appointed to the Kimberley subsidiary that held Ellendale used a legal loophole to shift responsibility for the clean-up to the state government’s industry-funded mining rehabilitation fund.

The rehabilitation costs at Ellendale have been estimated at between $28m and $40m. WA’s new Mines and Petroleum Minister Bill Johnston has flagged an overhaul to prevent “rogue elements” taking advantage of the MRF.

DeBeers Diamonds

De Beers Consolidated Mines (DBCM) is reportedly appealing to the Pretoria High Court in South Africa to set aside a decision by the South African Minister of Minerals Mosebenzi Zwane requiring DBCM to pay a levy on diamonds exported from South Africa to Botswana for the purpose of aggregation.

Although DBCM is apparently eligible for an exemption from this levy, even exceeding the required criteria, and has received such exemption every year since it was enacted in 2008, Mining Weekly reports that the Minister has made a decision to deny them the exemption for the 2017/18 period.

DBCM is now therefore taking the matter before the Pretoria High Court, asking them to set aside the Minister's decision, reports the news source.

De Beers taps into polished diamonds market with first-time auction

Anglo America - De Beers

Anglo American’s De Beers, the world’s largest rough diamond producer by value, has decided to begin selling its own polished diamonds in auctions for the first time in its history.

The pilot auction, scheduled for June, will include a wide range of polished stones manufactured directly from the company’s own rough diamonds.

"The pilot auction, scheduled for June 29, will include a wide range of polished stones manufactured directly from De Beer's own rough diamonds." All the polished rocks will carry grading reports from both the International Institute of Diamond Grading & Research (IIDGR) — De Beers’ in-house grading unit — and the Gemological Institute of America (GIA).

“We are interested in testing the level of demand from polished buyers for diamonds that have a clear and attractive source of origin, and that offer the assurance of product integrity that dual certification provides,” Neil Ventura, the miner’s executive vice president of auction sales, said in the statement.

If successful, the process would provide De Beers with more insight into the polished market, while also helping consumers fill gaps in supply or inventory if they were unable to find goods at the company’s rough auctions, he added.

All registered De Beers auction buyers will be eligible to bid in the first sale, which takes place on June 29.

US Wobble Takes Shine off Pandora Sales

Pandora jewellery

Pandora reported strong growth in the first quarter, but US store closures and sluggish mall traffic dented its performance stateside.

Global sales jumped 9% year on year to $756.9 million (DKK 5.16 billion), while net profit increased 4% to $199.7 million, the Denmark-based volume jeweler reported Tuesday.

The rise was mainly due to a 46% surge in revenue at Pandora-owned concept stores, which came to $270.4 million, driven by an increase in the number of stores. In the US, revenue fell 7%, or 10% in local currency.

While the company added a net 21 concept stores in the US in the past year, it closed about 600 other points of sale in the fourth quarter of 2016 and suffered from a decline in mall traffic, the retailer explained.

A one-off shipment to Signet Jewelers-owned brand Jared a year earlier also had an impact on the sales decline. “The retail climate in the US remains difficult, which was reflected in our performance in the US for the quarter,” said Pandora CEO Anders Colding Friis.

Important Advice on How to Sell Your Diamonds

How-To-Sell-My-Diamond HowTo Sell My Diamond

If you are you considering selling your diamond, but feel as though you have no idea how or where to begin with the process?

This article will give you a few tips to help you along the way.

TIP #1 Diamonds are usually given to display love, making the sentimental value higher to the seller than the actual value to a buyer. Should you be in the market to sell your diamond, make sure you are ready to part with the diamond before begining the process.

TIP #2 Be sure of the quality and authenticity of what you are trying to sell. Make sure of the quality and the grade of the stone. This is most important for the ultimate value of the diamond. There have been many instances where a seller is committed to selling their diamond only to find out the quality isn’t as described when originally purchased.

There are Jewellers or services available, who will give an unbiased assessment of your stone. But it is far more valuable in the long run to get a report from a recognised Laboratory.

It is also recommended to verify the report matches the Laser inscription before placing your diamond on the market, to assure your diamond is the same stone should it not sell.

TIP #3 Now that you have an accurate report of the quality, make sure you get a realistic selling value. Believing the diamond holds a higher value than it truly possesses will lead to a challenging, frustrating experience which can be dragged out.

An appraiser can assist you with determining a fair selling, price so you can avoid this pitfall. Diamonds are priced in US dollars, so your diamonds price will be affected when converted to your local currency.

A good way to see current retail values is to visit online stores like or

TIP #4 There are many ways to sell a preloved diamond or diamond jewellery. Research your selling options to make an educated decision that works best for you. Be it an online market or exploring options through a local jeweller or dealer, be sure you are using the best option for your needs.

Example, if time is not of the essence, an online market or an auction house could be the best way forward. If you want a quick sale, visiting your local dealer may be the best option.

DCLA Diamond Laboratory provides an internationally recognised and respected report to any seller or prospective buyer.

Gem Diamonds recovers 80 carat rough diamond

80 carat rough diamond

Another D colour Type II diamond weighing 80 carats has been recovered.

Shares in Gem Diamonds spiked on Thursday after the miner announced it had recovered one of the highest quality stones to come out of its Letseng mine in Lesotho.

The discovery of this 80 carat diamond comes less than a month after the miner announced the recovery of a 114 carat rough diamond. And two years after Gem Diamonds found a 357 carat rough diamond, which sold for $19.3 million.

Gem Diamonds has recovered four of the 20 largest white gem quality diamonds ever recovered, which makes of the Lesotho mine the world’s highest dollar per carat kimberlite diamond operation.

This Blue Diamond Is Natural—and Also Synthetic

Blue Diamond

The good news is, from everything we know, all lab-grown diamonds are detectable, and the detection devices are getting better and (somewhat) cheaper.

The bad news is that unethical people are still apparently devising new and innovative ways to cheat. Take GIA’s first sighting of a natural/lab-grown composite diamond with a fancy colored grade, which was first announced at the U.S. Jewelry Council forum on undisclosed lab-grown diamonds last week.

According to a GIA Lab Note published on Monday, the 0.33 ct. diamond was first graded fancy blue at the GIA’s New York laboratory. But what caught scientists’ attention was it had both nitrogen and boron defects. It is rare to see boron defects in a natural diamond—and even rarer to find both types of defects in one stone.

Further examination showed something else quite unusual: The stone was both type Ia and IIb diamond, another rare combination. (In fact, GIA reports running across that combo only once before, in 2009.) Finally, the truth was discovered. This was a colorless natural diamond with a small CVD coating on top. That coating gave it a fancy blue color when viewed from the table.

While the GIA note mentions that composites have been produced before, this is apparently the first composite GIA has discovered submitted (undisclosed) to its lab. This raises the possibility of more in the wild. This obviously is a troubling discovery—though someone with knowledge of the issue said at last week’s forum that he believes that GIA’s devices would be able to spot it.

Another lab exec told me producing these composites is likely not easy, or cheap, to do. But this will clearly be something to watch (and watch out for) in the future.

Graff Unveils 105-Carat D-Flawless Diamond

The Graff Vendôme

Graff Diamonds has unveiled the 105.07 carat D flawless pear shaped diamond, it has named the Graff Vendôme after its new retail outlet at Place Vendôme in Paris.

The diamond was cut from a 314 carat rough that was recovered in May 2015 at Gem Diamonds’ Letšeng mine, that was named “The Destiny” and sold into a partnership in June of that year according to a statement by the miner.

The stone was cut and polished by Graff’s own master cutters, who first used a 3D computerised mapping system to plan the cut and then laser cut and hand polished the stone over “many months”.

The rough yielded 12 other diamonds, the largest of which was 17.1 carats. Nine of them were of D flawless quality.

Letseng Mine Yields 114ct. Diamond

114ct rough Diamond

Gem Diamonds has found a 114-carat rough diamond at its Letšeng mine in Lesotho, the miner reported Friday.

The discovery of the D-color, type-II stone follows a drop in recovery of large diamonds at the mine, which yielded only five stones above 100 carats last year compared with 11 in 2015.

The deposit is one of the highest-value in the world by average price per carat, producing four of the 20 largest gem-quality white diamonds in history since Gem Diamonds acquired it in 2006.

De Beers, Luk Fook to Co-Brand Grading Reports

  Diamond Grading & Research (IIDGR)

De Beers’ polished-grading unit has partnered with Hong Kong-based jeweler Luk Fook to produce co-branded diamond reports for the retailer’s customers. 

The arrangement with the International Institute of Diamond Grading & Research (IIDGR) will enable Luk Fook to present customers with a magnified image of a diamond’s “light performance pattern,” giving them more information about the jewelry on offer, De Beers said Thursday. 

The program, which launched Thursday in Hong Kong and Macau, will potentially expand to other parts of Greater China at a later stage, De Beers added. 

“As customers continue to seek ever-greater confidence in diamonds, we are seeing increased demand from major diamond jewelry retailers for the innovative solutions that IIDGR can provide,” said Jonathan Kendall, the institute’s president. “This new initiative with Luk Fook highlights the rapid international growth we are seeing in the business, and we look forward to a long and successful partnership.”

GIA Finds Significant Undisclosed Synthetics

GIA Melee Analysis

The Gemological Institute of America (GIA) recently uncovered an unusually large number of undisclosed synthetic diamonds mixed in with natural melee diamonds, the lab confirmed with Rapaport News on Monday.

A parcel of 323 melee diamonds with an average size of 0.014 to 0.015 carats was found to contain 101 chemical vapor deposition (CVD) synthetic stones at the GIA’s Mumbai lab, reported Wuyi Wang, the institute’s director of research and development. The goods had been submitted to the GIA’s Melee Analysis Service, which made the discovery.

The GIA launched the service in December of last year and has regularly identified small quantities of undisclosed synthetic melee diamonds in some parcels submitted for analysis, Wang said.

However, he explained, “this is the first time we have seen such a significant percentage of CVD melee mixed with natural melee.” Fewer cases of undisclosed mixing have been reported recently as more testing facilities and detection machines have come to market, Praveenshankar Pandya, chairman of India’s Gem & Jewellery Export Promotion Council (GJEPC), said at the World Federation of Diamond Bourses’ Presidents’ meeting last month.

The first major discovery of undisclosed synthetics was in May 2012, when several hundred CVD diamonds were sent to the International Gemological Institute ??(IGI) in Antwerp and Mumbai to be certified as natural diamonds.? Still, concerns of such fraudulent activity are on the rise as synthetic diamond production increases, the GIA and De Beers International Institute of Diamond Grading & Research (IIDGR) said in separate presentations at last week’s Hong Kong Diamond, Gem & Pearl show.

Production has largely been focused on High Pressure-High Temperature (HPHT) synthetics, while you don’t see a lot of CVD melee in the market, Wang said in his presentation. Regardless, the risk of undisclosed synthetics has increased as synthetic-diamond growth technology has developed, especially in the very small melee sizes, given that the market has lacked an efficient, affordable means to detect them, the GIA said in its Monday statement to Rapaport News.

“The GIA has screened larger diamonds for treatment and to determine whether they are of natural versus synthetic origin for decades, but the small size and vast quantities have made doing the same for melee impossible until now,” the company said. “The GIA Melee Analysis Service gives the industry – as well as the consumer – confidence in knowing what they are getting for the most prevalent stones in the market.”

De Beers Profit Jumps as Diamond Market Stabilises

  De Beers Diamonds

Profit more than doubled for De Beers last year as trading conditions in the diamond-manufacturing sector improved and inventory levels stabilized.

Underlying earnings jumped to $667 million in 2016 from $258 million a year earlier, parent company Anglo American said in a statement Tuesday. This came as revenue grew 30 percent to 6.07 billion, reflecting a 37-percent hike in rough-diamond sales to $5.6 billion.

The midstream of the diamond industry returned to buying rough after a 2015 slump in demand that resulted from oversupply of polished and inflated rough prices. Manufacturers started working down their polished inventories in the second half of that year before restocking their rough supplies in 2016.

De Beers also lowered prices, with its rough-price index declining 13 percent across 2016. The miner consequently reduced its rough stockpiles during the year, management said. De Beers production fell 5 percent to 27.3 million carats, while sales volume leapt 50 percent to 30 million carats, meaning it sold a larger volume of stones than it mined. “2016 generally was a much better year for the diamond industry,” said Bruce Cleaver, De Beers chief executive officer. “The midstream performed much better than 2015, largely as a result of the strong and decisive action we took in 2015 to reduce production in accordance with demand.

The fruits of that tough action we took in 2015 was seen through 2016." The company projected production would rise to 31 to 33 million carats in 2017, “because we see the market has recovered from where it was at the end of 2015,” noted Cleaver. The company maintained a conservative outlook for the diamond jewelry market given prevailing global macro-economic conditions and geopolitical risk.

Performance will be dependent on a number of macro issues, including the attitude of the new U.S. administration, the strength of the dollar, continued recovery in China and the impact of Indian demonetization, Cleaver explained. “All other things being equal, we think diamond demand will continue to grow along with GDP growth,” he said.

HRD Uncovers Tampered Diamond Grading Reports

Peter Macken

HRD Antwerp has invalidated 156 diamond grading certificates and fired three employees who accepted a financial incentive for tampering with the reports at its Mumbai laboratory.

A Mumbai-based trader attempted to improve the grade of diamonds he submitted to the laboratory by enticing three full-time staff members, Peter Macken, HRD’s chief executive officer, told Rapaport News.

The client, a “one or two person” firm, has been banned from working with the grading company in future, while the employees admitted to their actions and were subsequently dismissed, Macken added. The diamonds in questions were submitted to the lab for their first grading.

HRD’s internal controls picked up on a discrepancy between the stated grade in two places. That alerted checkers to a problem, leading to their discovery that the reports had been tampered with. “We uncovered it pretty early on,” Macken (pictured) said. HRD filed a complaint with the local authorities and has engaged with external lawyers in India and Belgium. The company released a list of the reports under investigation, which relate to diamonds ranging from 1.01 carats to 3.96 carats with a combined weight of 327.25 carats.

HRD is offering a free check to anyone holding one of the documents. The list relates to reports that may have been affected, but not all of them were definitely altered, Macken stressed. “HRD Antwerp strongly believes that the most effective way to strengthen consumer confidence and safeguard the integrity of the global diamond trade is by making these acts public and by holding those who commit these acts fully accountable for their actions,” he said a separate statement.

RapNet, Rapaport’s diamond trading network, has removed and blocked the reports from its website. As of Thursday morning, 11 of the reports were on RapNet and have been removed, while 70 have been listed in the past but are no longer active.

59.60 carat pink

Sotheby’s teamed up with two other firms to collectively own the Pink Star diamond, which has been valued at $72 million.

In November 2013, the oval mixed cut, 59.60-carat, fancy vivid pink, internally flawless stone was sold to diamond cutter Isaac Wolf for a world auction record of $83.2 million in Geneva.

The gem was returned to Sotheby’s after Wolf defaulted. “Diacore and Mellen Inc. have acquired an ownership interest in one of the world’s natural treasures: the remarkable Pink Star diamond,” Sotheby’s said in a statement. “The three parties have formally partnered to achieve the value of the 59.60-carat stone, which Sotheby’s holds in its inventory.” No other details, including financial, were disclosed. However, a Sotheby’s annual report published in February 2014 shows the diamond was recorded in the company’s inventory at about $72 million.

It remains the largest internally flawless, fancy vivid pink diamond ever graded by the Gemological Institute of America, Sotheby's said. Diacore purchased the original 132.50-carat rough and took two years to cut and polish it, the statement added.

Diacore is a diamond manufacturer headquartered in Johannesburg, South Africa. Mellen Inc. is a family-run private jeweler based in New York.

The exceptional diamond was recoverd from a mine in South Africa, originaly named the Steinmetz Pink.

CVD Lab-Grown Diamonds with GIA Natural Diamond Certificates

CVD Synthetic diamond with GIA report for sale on leading online internet platform

Alibaba, the leading online internet platform for global wholesale trade, has sent special Trade Alerts by email to millions of potential diamond buyers, offering CVD Lab-Grown Diamonds with GIA Natural Diamond Certificates as one of its Top Products of the Week.

This offer is a blatant – and ostensibly fraudulent – attack on the Gemological Institute of America’s (GIA) product integrity. Made on behalf of a New Delhi-based supplier of synthetic diamonds and gem simulants, the offer is akin to selling a fake Rolex watch with a genuine Rolex certificate of authenticity and guarantee.

The offer was concrete and specific: the seller, the International Trading Corporation (ITC), claimed to have the ability to supply 10,000 carats of CVD diamonds a week. Priced at $100 per carat and above, each and every one of these CVD diamonds (i.e., pieces over 0.15 carats) carried a genuine GIA natural diamond report. If this was true, it might easily be the most serious marketing fraud in the diamond business ever. In response to our queries about this offer, GIA Senior Vice President Tom Moses said: “We will immediately investigate this fraudulent use of our certificates.” Alibaba’s Marketing Power The publicly traded Alibaba Group “reached a milestone of over 400 million annual active buyers,” said Alibaba’s CEO Daniel Zhang in his most recent quarterly review. “Our proven ability to deliver an unparalleled consumer experience and to help merchants attract, engage and retain buyers will drive future growth in our core business,” he added. It is that unparalleled global marketing power that enables innocuous, almost anonymous, unscrupulous entities to wreak havoc in the diamond world. Catastrophic Reputational Consequences for GIA Our first reaction upon receiving the Alibaba Trade Alert directly to our inbox was to think that the combination of synthetic stones with a GIA natural diamond report was a contradiction in terms. We believed that no bona fide diamond buyer could be that naive, and browsed the website of the seller (, seeking an explanation. Lo and behold, the ITC website gave the inexplicable explanation in bold letters: “Some of the CVD Diamonds when sent to Laboratories get passed as Natural diamonds, and hence they can be provided with GIA natural diamond certificates.” Is this plausible? Unlikely? Impossible? We have learned over the years that nothing is impossible. What makes the statement ridiculous, however, is the volumes this seller was offering. Could the GIA really “miss” up to 10,000 CVD carats a week and mistakenly issue natural diamond reports for them? Not in a million years. We thought it must just have been a mistake. But, what if out in the market, there are thousands or tens of thousands of synthetic diamonds inscribed with GIA certificate numbers corresponding to genuine GIA natural diamond reports? This scenario would not only be “the beginning of the end” of trust in both diamonds and diamond traders, but also catastrophic for the GIA and its reputation. Not a single diamond trader or consumer holding a numbered natural GIA certificate and a laser-inscribed diamond will ever suspect that his or her diamond may be synthetic. At least not until now. Purchase Inquiries and Price Quotes Assuming the ITC might be reluctant to the talk to the press, we asked a Dutch-based trader, Tyson Edgon, to approach someone calling himself Mr. Shobhit, who seemed to be the principal of the Delhi-based synthetic diamond trading company, to make an initial purchase for us and to ask some specific questions by e-mail. Complete and unequivocal answers were provided by the company. Tyson went ahead and first asked for price quotations for 20 round CVD synthetic diamonds (each of G color, VS clarity, and 0.95-0.99 carats) and for 30 round diamonds (G color, SI1 clarity, and 0.45-0.50 carats). The answer was quite surprising. The diamonds of just below one carat would come to $1,290 per carat, plus $298 per stone for the GIA natural diamond report and $50 per laser inscription. The almost half caraters would cost $780 per carat for G/VVS-VS. If we required SI1, the price would go down to $690 per carat. Comparing these prices to IDEX Real Prices, some goods were up to 70% below going market price, others were closer to the natural market prices. A separate inquiry was also made, which was directed at Rajesh Dubey, the name listed on the Alibaba offer as Head of International Sales at ITC. We asked for price quotations for “CVD diamonds sized 0.50-0.69 carats (some 75 stones) with GIA natural diamond certificate.” Dubey replied immediately: “We can supply the size you required at US$790 per carat. The cost of certificates will be $75 each. The order must be minimum 100 stones.” So, we had two separate, unequivocal, and quite similar price quotations. Tyson then followed this up with a request: “In the Alibaba publicity and in our [order] inquiry, it is specifically noted that these CVD goods come with a GIA Natural Diamond Certificate. Please confirm that this is indeed the case.” The answer: “YES, it is true. They will come with GIA certificate and laser inscription of GIA number written on the girdle of diamond. Plus they can also be verified at, GIA official website.” That could not be clearer. Stocks of GIA Natural Diamond Reports? We wondered whether the supplier had these goods in stock or whether they needed to be produced. This gives added meaning to the remark on the ITC website that the GIA “mistakenly” certifies CVD diamonds as natural. If there are not enough specific goods in stock, how can the company know beforehand that the GIA will “mistake” these lab-grown diamonds for natural diamonds? On Tyson’s aforementioned specific order, Shobhit replied: “We have 1.00-1.10 carat sizes, F-G-H, VVS-VS in stock, around 14 pieces as samples. Rest we need to cut and polish. The raw material is always in stock with us. The lead time of order fulfillment is 7-10 days.” That is miraculous, as the GIA takes 7-10 days to certify the stones. One wonders how they polish, certify and ship them in this time, and as a result our skepticism grew to suspicion. Tyson asked for a picture of one of the natural certificates that would come with a CVD diamond. Shobhit sent him GIA certificate 7206591355, a round brilliant of 1.05 carats, issued on August 10, 2015. We found the report on the GIA website. A further inquiry with Moses in New York, revealed that this diamond was a Type I diamond – thus it could not have been a CVD stone. The statement, therefore, on the ITC website claiming that these natural certificates represented grading mishaps by the GIA and that the laboratory had failed to recognize CVD, was clearly false. According to the ITC’s own “About Us” section on its website, the company only deals in synthetic and simulated gems, stating this fact repeatedly. However, the website also states: “Currently we are holding a stock of more than 25,000 IGI and GIA certified diamonds.” Let’s think about this – no, let’s not. I really don’t want to think about the possibility that the company has 25,000 falsely-certified diamonds. Some of the CVD diamonds offered to us have already been certified. [See detailed list.] An Indian Company that is Really Chinese The Indian company, by its own admission, acts solely as the sales office of a Chinese mother company. But strangely, it is emphasized that none of its products originate from China. “We do not deal in any kind of Chinese or Korean Products. Our products are made in Czech Republic, Austria, Egypt and USA,” says the ITC. Apparently the company’s main offices are in Shenzhen, China. The Indian sales office was reportedly established in 2009 “to provide better services to their customers located in international market.” There are also sales offices in the Czech Republic and in China. The invoice issued by the Delhi office also notes the address of the Shenzhen head office on its letterhead. Strangely, however, its registration for Indian VAT purposes was only completed in November 2014. So too was the website. What does the company say about itself? “With the experience of 50 years in the field of synthetic Lab grown diamonds & cubic zirconia, [we] are one of the oldest houses to cater the requirements of [our] esteemed customers in all their stimulated [sic] diamond needs. Along with serving its old customers, the company has created its unique identity in the market for machine-cut high quality synthetic diamonds and cubic zirconia.” For a 50-year-old company it lacks any “visible” history either on records or on the Internet. Synthetic Diamond Sources Unknown Where do the CVD raw materials come from? We really don’t know – at least not yet. Maybe the FBI will be able to find that out. The website asserts that “synthetic lab-grown diamonds [are] made [by] CobLabs Hong Kong Limited and [our] HPHT/CVD synthetic diamonds can pass all [natural] diamond testers. The company has got tie-ups with top brands so as to deliver the right quality and its consistency to their customers.” This one simple line impugns the credibility of all synthetic diamond detection devices. We searched the Internet, company registration records in Hong Kong, and in every data bank we could find. There was no CobLabs in Hong Kong. Then we checked Internet domains. Lo and behold, we found a COBLABS.COM domain registration. The registered owners and domain operators are – make one guess – International Trading Corporation in New Delhi. That website is not active. The domain registration has expired – it can be picked up for $8. Who is ITC? We subsequently checked “International Trading Corporation.” Apparently, it does not exist as a limited company. We only found an address. Their invoices have a VAT number (called TIN number in India). The number was indeed issued in the name of International Trading Corporation, but the address was entirely different. It seems to be a residential apartment address – not a corporate location and not the address on the invoice’s letterhead. Maybe, just maybe, the whole organization is just a few con-men, determined to make a fast buck – and disappear when exposed. Or perhaps they are “freelancers,” employees of a larger company massively engaged in this fraud. What is real, however, is the bank. The YES Bank Ltd., India’s fifth largest private sector bank and founded about a dozen years ago is a “Full Service Commercial Bank.” At the very least, the account seems real. We refrained from contacting the bank and have yet to pay for our outstanding diamond invoice. My own bank, when learning why DIB suddenly wanted to make a diamond purchase, warned me. I was told that if the product I purchase is “fake,” and if the sellers can be suspected of being engaged in illegal activities, there may be a reasonable chance that the Indian anti-money-laundering authorities may actually confiscate the account – and my money. I may end up paying money for nothing. Suspicions about the Fraudulent Scheme Moses confirmed that he has been aware for some time of an active trade in genuine GIA certificates – and only in the certificates, separate from the diamonds. Many traders and jewelers have a GIA certificate that is used as a basis for in-store certification or for jewelry sales where the consumers are not really interested in certificates. “When you sell a tennis bracelet, the consumer is not getting a bundle of a few dozen GIA certificates,” confirmed one jeweler. There are millions of genuine GIA certificates in circulation, and it may not be ruled out that these are being purchased by unscrupulous parties. If that would be the case, a CVD manufacturer or trader could simply cut and polish a synthetic stone in conformity with the certificate specifications – easily making a stone of the same weight and proportions. “We know that this has happened,” admitted Moses. Another option is going onto the GIA website, randomly selecting some certificates, and then simply manufacturing a CVD diamond accordingly. The number on the girdle will allow the owner or buyer of a stone to verify the quality and characteristics of his or her diamond, even without having a certificate. And, of course, there is also a possibility that false certificates are being printed. This brings us back to the Rolex comparison: fake watches with fake documentation. Options Open to the GIA The disclosures made in this Intelligence Briefing may be one concrete, though isolated example of fraud or it might turn out to be the tip of the iceberg. For all practical purposes, this disclosure might mean that there may be hundreds or even thousands of GIA-certified undisclosed synthetic diamonds in circulation that may have the same number of the real stone on their girdles. Some of these duplicate numbered stones may be synthetic, some others may be of another simulant. They may also just be an inferior quality natural diamond recut to the precise measurements of a GIA certificate. As we said, we know this has also happened. Establishing a Chain of Custody for Certificates? It comes down to controlling the value chain or as some call it, the chain of custody. This also applies to GIA certification. One of the ideas floating around to counter such possible fraud would be to require the registration of every new owner of an issued GIA certificate. This would mean that just as with many other branded products, the owner would register their details. The diamond industry would most likely vehemently oppose such a move. Maybe a pilot project for large goods could be considered. However, in the end, it becomes a commercial cost-benefit analysis for the GIA. The GIA will need to do its utmost to defend its brand – which will also be in the best interest of the entire diamond industry. Though the industry is often reluctant to involve police, this is an instance where the FBI and India’s Central Intelligence Directorate (CID) should be called in. The FBI, the Indian police, and lawyers, through legal actions against those who cause damage to a product, may solve specific isolated instances of fraud. But this does not solve the issue itself. Let’s wait and see what both the industry and the GIA will do.

Six More Arrested in GIA Hacking Case

GIA to remove the fraudulent reports

Six more people have been arrested in relation to the hacking of Gemological Institute of America (GIA) diamond-grading reports by outside parties as the investigation into the case continues.

A total of eight arrests have now been made as a result of cooperation between the GIA, the Indian authorities and Tata Consultancy Services (TCS), the contractor that supports GIA databases, according to a GIA statement January 26.

In another development, the GIA has extended its submission date for the confirmation service for members of the trade concerned about the validity of their grading reports by two months to March 31, 2016.

Members of the trade with a GIA report originally issued between November 2014 and October 2015 who are concerned about its validity may submit the original report and the referenced diamond to any GIA location at no charge by the new deadline.

To date only 297 of 1,042 invalidated reports have been returned to the GIA. As of November 26, only 175 of the reports had been returned and two arrests had been made.

“It is imperative that all of the diamonds and their reports be returned to GIA to remove the fraudulently altered reports from the market,” the statement said.

De Beers Rough Diamonds

De Beers the sold $540m worth of diamonds in its first of sale of the year more than double the value of the sales achieved in the final sight of 2015.

Prices for rough diamonds softened last year because of an oversupply of diamonds in the production centres forcing companies such as De Beers and Alrosa, to cut their supply of rough to the market in an effort to restore prices.

Rough diamond demand broadened across the entire range as cutting and polishing factories began to increase their production.

De Beers has said it will change the way it operates its sights to become more flexible and responsive to its clients.

‘Harsh’ prison sentences given in bribery case.


Antwerp The Correctional Court in Antwerp handed down “extremely harsh” sentences and levied “substantial fines” against four diamond traders accused of bribing a grader at HRD Antwerp to give their diamonds higher color grades than they deserved.

The Antwerp World Diamond Centre (AWDC) announced the sentences via a press release circulated Monday titled “No mercy for those involved in certification fraud.” On Tuesday, an AWDC spokesman said that the traders received up to 30 months in jail, 15 of which is effective immediately.

Although the AWDC is not releasing their names, the spokesman did reveal that three of the traders are from India--from Surat, Bhiwandi and Mumbai--and were managers of Belgian diamond companies. The fourth is from Sierra Leone.

The grader, whose name also is being withheld, received a “heavy” sentence as well, 18 months in jail, 9 of which is effective immediately, and a substantial fine in the case.

The AWDC did not have specific information on the amount of the fines. Judicial authorities in Antwerp could not immediately be reached for further comment on the case.

The HRD Antwerp grading bribery case dates back to March 2012, when news first surfaced that the lab fired a total of four graders for what it called at that time an “unprofessional act.” That June, a total of four people--reported to be two diamond traders, an HRD employee and a “facilitator”--were arrested in connection with the case.

The AWDC said there is another firm allegedly involved in the case and that the public prosecutor in Antwerp is submitting an appeal to enable this firm to receive an “even heavier” sentence.

HRD Antwerp corporate statement regarding the deliberate provision of incorrect diamond certificates by employees in 2012.

Last week, the Correctional Court of Antwerp delivered a verdict in regards a case concerning the deliberate provision of incorrect diamond certificates by employees in 2012. Following the verdict, the Court imposed severe sanctions on the involved parties including effective incarceration, forfeiture of certain rights and substantial financial penalties and compensations. At the start of the process in 2012, HRD Antwerp and parent company AWDC both have declared themselves civil party due to significant reputational damage. Throughout this case, HRD Antwerp has had full confidence in the investigation by the prosecutor's office but has never been directly involved. The involved diamond companies and their representatives have since been declared persona non grata and are no longer customers at HRD Antwerp. The involved employees where immediately fired due to severe professional errors. “HRD Antwerp fully supports the recent ruling of the Court in regards this unfortunate case. It’s extremely important such violations do not remain without consequences. The imposed sanctions are therefore a strong signal towards the industry that such practices are not tolerated. We like to thank our customers for their loyalty and confidence despite this isolated case” says Peter Macken, CEO HRD Antwerp.

IDC Diamond Grading Laboratories use cold laser, this is why.

hot laser damage in diamond

It is important to understand there are two very different categories of lasers used for diamond inscription; hot lasers and cold lasers. Hot lasers are YAG lasers and Cold lasers use Excimer laser technology.

Simply put the PhotoScribe Cold laser system is the only laser system guaranteed 100% safe for diamond inscriptions.

Hot lasers will chip or fracture diamonds. High quality polished girdles are especially at risk for fracturing or chipping with "Hot" lasers.

The picture is a classic case of the damage done by hot laser. This will lower the value of your diamond by changing the clarity grade or polish grade of the diamond.

Make sure your diamond is Cold Laser inscribed before you buy it.

ISO International Standard, welcomed by CIBJO

DCLA adheres strictly to the IDC and Cibjo rules.

All laboratories must have DIAMOND on the report or certificate.

DIAMOND is used exclusively for diamonds of natural origin. In layman’s terms, if your diamond certificate or report does not state clearly DIAMOND IE: NATURAL DIAMOND on the certificate then is not compliant or working to Cibjo or IDC rules adopted by the ISO. This means the laboratory has not tested or proven the stone to be of natural origin.

MILAN, ITALY: JULY 27, 2015 - CIBJO has welcomed the publication of ISO International Standard 18323, entitled "Jewellery - Consumer confidence in the diamond industry," which specifies a set of permitted descriptors for the diamond industry that are designed to be understood by consumers. The new ruling by the International Standards Organisation explicitly defines a diamond as having been "created by nature" and further notes that "the denomination 'diamond' without further specification always implies 'natural diamond.'"

The new ISO International Standard mirrors the definitions outlined in CIBJO's Diamond Blue Book, which are aligned with those of the International Diamond Council (IDC). The Diamond Blue Book, the IDC Rules, and also the PAS 1048 documents, relating to terminology and classification of grading polished diamonds that were developed by CIBJO with the support of the German Standards Institute (DIN), were cited as the primary sources in the ISO International Standard's bibliography.

See: how to read a DCLA certificate. DCLA diamond grading reports are only issued for natural untreated and unenhanced diamonds. Therefore every diamond report issued by the DCLA has the term NATURAL DIAMOND clearly noted at the top of the certificate.

De Beers sightholders refuse boxes Update

De Beers

De Beers’s the world’s largest rough producer felt the pain, when only $300 million of the $450 million estimated sight was taken up by their sightholders. This leaves 30 percent of the rough on offer  on the table.

Anglo has previously counted on diamond revenues to offset a collapse in the price of other metals and minerals it mines. Anglo may cut the company’s dividend for the first time since 2009 according to analysts.

This is an indication of turmoil in the $80 billion diamond industry as traders, cutters and polishers suffer from a poor liquidity and weaker demand for jewellery.

Producers in India, where 90 percent of rough diamonds are cut and polished, may halt imports over the supply glut.

Update: Report sightholders may have refused 35%-50% at July sight which may be as low as $200M.

Hundreds of diamonds recalled by the GIA

GIA colour treated diamonds recalled

Diamonds certified by the GIA had an undisclosed treatment which fades over time, but improves their colour by as much as three grades.

GIA is asking anyone in trade stocking these potentially treated stones to turn them back into the GIA for re-examination.

The majority of the GIA certified diamonds are one carat or larger, with a number of three to five carat diamonds.  A colour grade of three higher in these sizes amounts to a very big difference in price.

GIA has terminated the client agreements with companies suspected of knowing the diamonds were treated and did not disclose it. 

GIA discovered the treatment when a client who purchased one of the diamonds resubmitted it to GIA for re-check.

It was then that the GIA connected this stone with hundreds of treated diamonds submitted by the companies.

The GIA has notified industry bodies about the still unidentified temporary treatment.

SA diamond trader gambled the money away

Diamond Dealers Club South Africa

An unnamed diamond trader is suspected of stealing diamonds valued at around US$1 million from several dealers in the Johannesburg diamond center in South Africa, according to a report in The Star.

The diamonds were apparently handed over to the diamond trader with the expectation that payment for them would be made within a few days, as is the custom in the diamond trade. The news source says an industry insider told them that the man was known to have a gambling problem and it was discovered that he had pawned the diamonds and gambled the money away over a period of two weeks.

The diamond trader is said to be in hiding, and his life is believed to be in danger.

South African Diamond Dealers Club Treasurer Michael Ellis is quoted by the news source saying that he is aware of the incident, and that the man is not a member of the Diamond Dealers Club, although he is known within gem circles. "You get a few incidents like this ever so often, but it happens with fringe members, not mainstream dealers," said Ellis, as quoted by The Star, adding that when any theft takes place, a ban on the dealer is placed worldwide, meaning that they will never be able to work in the industry anywhere in the world.

Tough rules for De Beers diamond customers

De Beers

Biggest reforms in a decade from De Beers’s over concerns of the financial stability and transparency of their sightholders.

The world’s largest supplier by value is changing the deal, introducing tougher rules for companies wanting to join its coveted group of sightholders.

De Beers will also insist customers hold a specified proportion of equity in their businesses, making them less reliant on bank borrowing.

Bank finance has receded and no new banks are coming forward after Antwerp Diamond Bank closed to new business in September.  Over the past two years banks have cut credit lines to the diamond trade, causing liquidity problems and a sharp fall in rough diamond prices.

The De Beers group which sells $6bn of unpolished diamonds annually will clarify the financial situation of all the companies. The belief is transparency will benefit the whole sector.

Brown Diamonds natural or synthetic

Cognac, Champagne or Chocolate diamond

Causes of colour in heat treated brown diamonds and synthetic brown diamonds are similar to treated pink diamonds.

In natural diamond the colour is related to a lattice imperfection. This can be mimicked in synthetic or treated diamond by a variety of treatments including annealing, heating or irradiating. The heat and pressure or irradiation can result in the lattice deviation resulting in the brown or pink colour.

Synthetic brown diamond is created by compressing graphite under extreme pressure and heat to above 1500 Celsius. The treatments were perfected in several laboratories in Russia, United States and China.

Lazare Kaplan Internationals Belgium subsidiary Pegasus Overseas Ltd marketed the General Electric processed diamonds under the name GE POL or in the USA as Bellataire.

This led to a technique for creating, or treating brown diamonds into higher valued colours like yellow or colourless diamond.

The disclosure of the treatment is noted by the “GEPOL" inscribed on the girdles of every treated diamond.

Brown diamonds are often marketed with expensive sounding names like Cognac, Champagne or Chocolate diamonds. Natural brown diamonds are a cheap alternative to more expensive colours.
