Twenty five undisclosed lab grown diamonds have turned up at the Gemological Institute of America (GIA) including several with a rare greenish color.
The GIA’s lab in Carlsbad, California, recently received the stones weighing from 0.46 to 0.52 carats for grading reports. They all proved to have been created using High Pressure High Temperature (HPHT), GIA senior research scientist Sally Eaton Magaña explained in a lab note published in the Spring 2019 issue of Gems & Gemology, the institute’s quarterly scientific journal.
While nine of the stones were colorless or near-colorless, eight had faint yellow green color, seven were faint green, and one was very light green. The coloring resulted from a high concentration of nickel, an impurity that’s common in HPHT, but rarely in large enough amounts to affect the color, Eaton Magaña explained. (In diamonds at large, nickel can cause a green hue.) GIA gemologists previously reported on a fancy deep yellowish green HPHT diamond in 2017, with nickel also the cause in that case.
“As laboratory grown diamond manufacturers continue to experiment with their recipes and the process further evolves, we will likely see greater quantities and a wider variety of color ranges,” Eaton Magaña wrote. The occasion also gave a rare opportunity to analyze a large dataset of similar but unusually colored HPHT diamonds, she noted.
The Spring edition of Gems & Gemology also reported on a natural diamond with a synthetic layer the second such case the GIA had seen in about two years.
Lucapa Diamond Company has recovered its first+100 carat diamond for its Mothae mine in Lesotho.
The stone is a gem-quality 126 carat diamond and is the largest diamond recovered since commercial mining operations commenced in January 2019.
The diamond is also the sixth +50 carat diamond recovered since Lucapa commenced its pre-production bulk sampling programme at Mothae in 2018.
It comes shortly after Lucapa and its partners recovered a 130 carat gem-quality diamond from the company’s high-value Lulo alluvial mine in Angola.
Lesotho Minister of Mining, the Honourable Keketso Sello, said the recovery of the 126 carat diamond represented another milestone for Lesotho’s highly-prospective diamond sector.
“Lesotho is very proud of its international reputation as a producer of large and high-quality diamonds and this latest recovery from our newest mine, Mothae, continues to demonstrate our nation’s great potential,” said minister Sello.
Lucapa MD Stephen Wetherall said the 126 carat diamond was further proof of the large stone and high-value nature of the Mothae kimberlite resource, which is located within 5 km of Letseng, the world’s highest US$ per carat kimberlite diamond mine.
“We are delighted to have recovered our first +100 carat stone so early in our commercial mining
campaign at Mothae, along with other rare Type IIa and fancy coloured gems, and look forward to
unlocking the true value of this mine over the next decade and beyond,” Wetherall concluded.
RapNet, the world’s largest diamond trading network with daily listings of over $7.4 billion, will be voting on whether it should provide diamond listing and pricing services for synthetic diamonds. Voting will be limited to registered RapNet members who log in to RapNet.com and will take place from Sunday May 26 through Friday May 31, 2019.
The results of the vote will be announced at the Rapaport Breakfast on Sunday June 2, 2019, at the JCK jewelry show in Las Vegas, Nevada. The keynote address at the breakfast entitled “Synthetic Ethics” will be presented by Martin Rapaport. The Rapaport Breakfast is open to the jewelry trade and media. Registration and information is available here. The breakfast and additional Rapaport “Ethical Sourcing” and “Appraiser” Town Hall Meetings will be broadcast live on Facebook here.
The issue of synthetic diamonds is hotly debated in the diamond and jewelry trade. Recent decisions by the US Federal Trade Commission (FTC) have removed the word natural from the definition of a diamond. The FTC believes that diamonds need not be natural to be described as diamonds, although they require disclosure when a diamond is “man-made” or “laboratory-created.” Martin Rapaport has published an important article about the issue entitled “Synthetic Ethics” that can be reviewed here.
The vote will provide RapNet and the jewelry industry with important input as to the role of synthetic diamonds in the diamond trade. The final decision regarding the matter will be made by the RapNet management team.
“Synthetic diamonds present significant challenges and opportunities to the diamond trade. The role of natural diamonds is threatened as synthetic diamonds offer consumers lower prices and provide retailers with higher profit margins. The problem with synthetic diamonds is that they are not a store of value as they have no natural scarcity and can be manufactured with unlimited supply. Their prices are expected to decline over the long term as their cost of manufacturing falls. The diamond trade must decide if they want to trade in long-term integrity for short-term profits,” said Martin Rapaport, Chairman of the Rapaport Group.

The ICO that was promoted as a game-changer on the diamond market faces a dramatic fall from grace.
The U.S. Securities and Exchange Commission (SEC) has pulled the plug on a $30 mln cryptocurrency Ponzi scheme called Argyle Coin. The company, which promised to turn fancy colored diamonds into globally accessible assets, defrauded more than 300 investors.
No diamonds for you
Who told you that colored diamonds are only for ultra-rich individuals? Argyle Coin allowed the average Joe to invest in one of the rarest diamonds in the world. The project was presented as a Blockchain-powered marketplace for trading these precious rocks.
According to the SEC’s press release, Argyle Coin was nothing more than a Ponzi scheme that defrauded new investors in order to pay returns to the old ones. On top of that, Jose Angel Aman, the man behind this scam, used investors’ funds in order to enrich himself (he bought real estate and horses). Overall, those who wanted a piece of luxury ended up losing $10 mln.
As alleged, Aman operated a complicated web of fraudulent companies in an effort to continually loot retail investors and perpetuate the Ponzi schemes as well as divert money to himself,” said Eric I. Bustillo, Director of the SEC’s Miami Regional Office.
Old story, new names
Argyle Coin was supposed to offer its clients a ‘risk-free’ investment opportunity given the ICO is backed by over $25 mln of fancy colored diamonds that are securely stored in the London-based Malca-Amit vault.
Notably, prior to Argyle Coin, Aman had managed to pull off two similar scams – Natural Diamonds and Eagle. Aman was charged with violating securities law antifraud provisions.
The Gemological Institute of America (GIA) has discovered a synthetic layer that improved the weight and color of a natural diamond, and has warned that the phenomenon may be happening more often.
The cushion modified brilliant, 0.64-carat stone contained about 0.10 carats of chemical vapor deposition (CVD) diamond, the GIA estimated in a lab note last week. The lab-grown layer was greyish-blue, in contrast to the natural section’s yellowish color, giving the combined stone a fancy-greyish-greenish-blue appearance.
This was not the first time a stone of this type has turned up at the GIA: In 2017, it reported on a 0.33-carat, fancy-blue diamond that featured a CVD overgrowth similar to this one.
“With the second of these composites seen at GIA, this could be a new type of product entering the market,” research associate Troy Ardon and analytics technician Garrett McElhenny wrote in the note, which the GIA published in the Spring 2019 issue of its quarterly scientific journal, Gems & Gemology. “The resulting color was likely the main motivation for growing the CVD layer on top of the natural diamond, though the extra weight gained could also be a factor.”
The stone’s unusual nature came to light after testing indicated it had features of both type Ia and type IIb diamonds — a rare combination. It appeared to have absorbed both nitrogen — a feature of type Ia diamonds that gives yellow color — and boron, which is present in type IIb stones and can turn them blue. “Mixed-type diamonds always call for additional scrutiny,” Ardon and McElhenny explained.
The pavilion — the section from the girdle to the bottom — showed natural growth features during fluorescence testing with DiamondView, a De Beers machine for identifying synthetics. However, the crown displayed characteristics of CVD, proving that manufacturers had grown CVD diamond over a natural base. Using computer modeling, the research team was able to calculate the weight of the synthetic part as approximately one-tenth of a carat.
The stone was well disguised: Numerous readings of its photoluminescence showed no indication of any synthetic origin, despite the fact that such tests are usually effective at revealing CVD. This may be because the lab-grown layer was so thin, the note pointed out.
“Natural diamonds with synthetic diamond grown on the surface require extra scrutiny due to the presence of natural-looking features, both spectroscopic and gemological,” the authors continued. “Careful inspection still reveals the presence of synthetic indicators, which expose the true nature of the diamond.”
There are a select few necklaces that might be deemed jewelry royalty Marie Louise’s diamonds from Napoleon, the Maharajah of Patiala’s bib, Daisy Fellowes’s Tutti Frutti, the Duchess of Windsor’s Zip, and of course, the one made by Cartier in 1975 to resemble two fully articulated crocodiles and using 1,023 yellow diamonds, 1,060 emeralds, and two cabochon rubies for Mexican actress María Félix.
Félix’s necklace was based on her own pet croc she even brought it into the store to make sure Cartier got it just right. She even suggested they live there for a while, just in case. Only one person other than María Félix has ever worn that necklace, now owned by the Cartier Collection.
In 2006, actress Monica Bellucci paired the necklace with a crisp white shirt for the red carpet at Cannes.
Over the weekend, on that same red carpet, Bellucci wore Cartier’s one of a kind diamond and emerald necklace made in tribute to the iconic piece and created by the same artisanal sculptor who brought María Félix’s little pets to life.
The María Félix Tribute necklace is in all diamonds and emeralds totaling 46.45 carats, and is by all reports “strikingly realistic with a body and legs ready to move!”
The crocodile necklace is of course but one proud member of the Cartier menagerie. The Panther, brought to three dimensional life in 1948 for the Duchess of Windsor, being the most iconic.
To make sure those diamond and onyx figures looked ready to pounce, legendary Cartier jewelry Director Jeanne Toussaint made all her designers spend quality time at the Paris zoo.
Russia’s major diamond mining firms including Alrosa have urged India to amend consumer laws on synthetic diamonds so that there is clarity on the quantity of synthetic diamonds entering the country and how they are being used.
Industry executives said that around 5 million carats of synthetic diamonds are produced globally, and the volume is increasing, causing concern to rough diamond producers. A senior executive, who did not wish to be identified, told the Economic Times that a meeting was recently held between India and Russia on synthetic diamonds.
“India is the chair of the Kimberley Process Certification System (KPCS) for 2019 and the Russian Federation is the vice chair. The KPCS is a joint initiative of 54 members, including India and the European Union, to stem the flow of ‘conflict diamonds’ that are used by rebel groups to overthrow legitimate governments.
It came into effect on January 1, 2003 through a United Nations General Assembly Resolution and includes governments, civil society and industry.”
“During the meeting between Aleksey Vladimirovich Moiseev, the KPCS vice chair 2019 and deputy minister of finance of the Russian Federation Peter Karakchiev, Alrosa’s head of international relations department and other senior representatives of the Russian foreign office it was decided that the KPCS should work towards having separate HS (harmonized system) code implemented for synthetic rough diamonds at the national level and encourage participant countries to expedite the process of implementation.
A diamond bought in memory of late diamantaire Sam Abram sold for more than double its high estimate at Christie’s Geneva auction Wednesday.
The cushion brilliant-cut, 118.05-carat, fancy-yellow, VS2-clarity stone fetched $7.1 million, or $60,000 per carat, at the Magnificent Jewels auction. The diamond, which was estimated at $2.5 million to $3.5 million, was purchased by Siba Corp. in honor of its former president. The company subsequently named it The Siba Diamond.
Three ruby pieces broke the top 10, all selling for well above their estimates. A 22.86-carat Burmese ruby ring by Harry Winston went for $7.2 million against its high estimate of $3 million, a final price of $314,900 per carat. Meanwhile, a Van Cleef & Arpels ruby and diamond necklace, which was valued at $400,000 to $600,000, garnered $2.4 million, and a ruby and diamond bracelet by the same jeweler fetched $1.6 million. That piece was estimated at $150,000 to $250,000.
A necklace comprising 110 natural pearls achieved $5.8 million, well above its high estimate of $3.5 million. All other pearl pieces of note offered at the sale also exceeded their original estimates, Christie’s said.
Other notable lots included a pear-shaped, 75.61-carat emerald pendant necklace that belonged to the Grand Duchess Vladimir of Russia, which sold for $4.3 million, or $57,300 per carat. It was estimated at $2.3 million to $3.5 million.
“Natural pearls and jewels with noble provenance, such as the 75.61-carat emerald from Grand Duchess Vladimir of Russia, found much acclaim and sold for far above their presale estimates,” said Rahul Kadakia, Christie’s international head of jewelry. “Also of note was the 118-carat, fancy-yellow diamond that was purchased by Siba Corp. in honor of Sam Abram, a prominent figure in the jewelry world, who very sadly passed away last week.”
In addition, the rectangular-cut, 25.27-carat, D-color Jonker V diamond connected to Anglo American founder and former De Beers chairman Sir Ernest Oppenheimer fetched $3 million against a valuation of $2.5 million to $3.5 million.
Christie’s sold 87% of all lots on offer, it said. The sale brought in a combined $62.1 million.
More than 110,000 Western Australian couples have celebrated a special occasion featuring a piece of Rosendorff’s fine jewellery.
An announcement to the Australian Securities and Investments Commission (ASIC) said a meeting of creditors was set to get under way at 11am Thursday.
Richard Tucker of KordaMentha Restructuring, appointed receivers and managers of Rosendorff Diamond Jewellers, said the business was holding too much stock.
“We are running a short highly discounted sale through the store to materially reduce the current stock levels whilst a sale or recapitalisation of the business is pursued,” Mr Tucker said.
I have always loved the mystique of diamonds. I’m attracted to the joy and romance they bring to their beholders
Craig Rosendorff “It is a tremendous opportunity to acquire a very special jewellery item at very competitive prices and may also help save an iconic Perth jeweller.”
He said a secured creditor would support the receivers to ensure current special orders, repairs and lay-bys were completed in time for the special occasions they might be destined for.
“From proposals, to weddings and anniversaries, we understand the importance and significance these items have on people’s special memories,” Mr Tucker said.
Daniel Hillston Woodhouse of FTI Consulting has been appointed as administrator.
Rosendorff is an iconic West Australian luxury business specialising in diamonds and bespoke jewellery design headed by Craig Rosendorff.
In 1975 Mr Rosendorff renamed and launched what became one of the longest-standing diamond companies in Australia.
His rags to riches story has been dubbed The Diamond Dream.
“I have always loved the mystique of diamonds,” he says on the company’s website.
“I’m attracted to the joy and romance they bring to their beholders, the heritage and their connection to families across generations.”
The large, glamorous showroom in the centre of Perth on Hay Street has been the setting of many magnificent parties and events showcasing the designs of the Rosendorff team.
Mr Tucker said gift cards and store credits would be honoured while trade continues.
White knight rescues collapased Rosendorff Diamond Jewellers
The Rosendorff fine jewellery business will carry on but under new ownership following a deal struck by receivers appointed last month.
Insolvency firm KordaMentha confirmed today it had struck an agreement to sell the business set up by Craig Rosendorff in the 1980s to an unidentified WA buyer also involved in the jewellery trade.
The deal, expected to be finalised in two to three weeks, guarantees more than 20 jobs and covers the Rosendorff trading name, stock and intellectual property.
Receivers from KordaMentha were put into Rosendorff Diamond Jewellers at the end of April.
The business, which owes at least $4 million to creditors, has shrunk on falling sales in the past three years to just its flagship store in Hay Street Mall.
The deal covers the Rosendorff trading name, stock and intellectual property.
Today’s sale announcement coincided with news the receivers are stepping up a discount sale which has already brought in between $2 million and $3 million.
The West Australian revealed yesterday that administrators from FTI Consulting had identified “irregularities” in the company’s accounts while sheeting home blame for the collapse to the mining downturn.
They questioned a $1.8 million shortfall in stock and four transactions totalling $170,000 where jewellery “left the store without payment”.
FTI said “there were limited controls around the accounting and inventory functions, which have led to some anomalies in the financial accounts”.
However, it noted that such irregularities were not uncommon, and there is no suggestion of any wrongdoing by Mr Rosendorff.
The firm’s statutory report on Rosendorffs also noted that Mr Rosendorff, who has invested millions of dollars in the business over the past 30 years, had drawn increasing amounts out of the company as its financial situation deteriorated.
Between July 2017 and FTI’s appointment, those withdrawals totalled $1.8 million, including $582,000 in the past 10 months.
The administrators says Rosendorffs had been under financial pressure for two years, citing “cash leakage” and a steady decline in sales after 2011, triggered by the end of the mining boom.
Gordon Brothers is owed about $2.2 million, Rosendorffs’ staff $400,000 and trade creditors $270,000.
