GIA Spots Broken Diamond Glued Back Together

Green diamond glued

The Gemological Institute of America (GIA) has identified a stone comprising two halves of a diamond that had been stuck together with an “unknown adhesive.”

Graders noticed a large fracture and cavity on the table of the marquise-cut, 1.38-carat polished diamond submitted to the GIA’s laboratory in Carlsbad, California, for colored-diamond testing. When the gemologists examined the crack under a microscope, they noticed a gap running down the stone from the crown to the pavilion, as well as a slight misalignment in the facets and air bubbles inside the fracture.

The polish lines on the stone’s facets would have linked if there hadn’t been a fracture, GIA gemologist Troy Ardon explained this month in a lab note in the latest edition of Gems & Gemology. For that reason, gemologists determined that the stone had been broken in half after it was at least partially polished, and then repaired with an unidentified adhesive.

“Diamonds have been adhered together with glue to form a diamond-doublet, but a broken diamond that has been repaired was not something previously reported by GIA,” Ardon added.

The GIA couldn’t grade the diamond because the 4Cs wouldn’t apply to it, the note continued. A carat weight would have been meaningless, as it would have comprised the weight of both halves plus the adhesive.

Manufactured diamonds will be to mined diamonds what Tudor is to Rolex

Manufactured diamonds

It’s no secret that Israel is one of the largest suppliers of cut diamonds the world over. And, if you have ever bought an engagement ring, chances are you have likely been presented with the option of buying an Israeli diamond.

According to USTradeNumbers, Israel ranked 22nd in total global trade this year with a total of $18.37 billion. Of that, more than $6.5 billion came from the importing and exporting of you guessed it diamonds.

I recently read a story published in Canada’s Financial Post titled, “A diamond may be forever for some but for millennial it’s looking like not so much”, lamenting the potential demise of the mined diamond industry.

In it, the author states:

the millennial generation poses an existential dilemma for the industry: they tend to spend on experiences rather than luxury items, achieve financial maturity later in life and are less likely to get married than previous generations.

It’s an interesting argument to be sure. And, if true, this trend could pose challenging for countries like Israel who rely so heavily on the art of refining mined diamonds.

The story goes on to argue that it’s not just the lifestyle choices of millennials that pose a threat to the old adage that diamonds are a girl’s best friend it’s the growing popularity of something called artisan or lab created diamonds.

Yeah, I’m not so sure I agree with that.

Many in the media have been making the same argument about the luxury watch industry for years now. While quartz  and other digital offerings may well be more accurate than mechanical wristwatches, the appeal to aficionados and luxury buyers is simply not there. Same for smart watches, which, to be sure, have a place among the masses and those interested in fitness, but do not affect demand for brands like Rolex, Cartier or Patek Philippe. Someone who wants a Rolex simply will not buy an Apple Watch as an alternative and call it a day. It’s like comparing apples and oranges.

While these manufactured stones may well be incredibly difficult to distinguish from mined diamonds, even to the most well trained gemologist, I am not convinced they will take much if any market share from those who truly want to buy a traditional diamond.

Now don’t get me wrong, I’m not saying the mined diamond industry isn’t susceptible to demand changes. Surely the past few years have illustrated it is indeed possible. I’m also not suggesting no one will buy this new type of jewelry stone. Some people will choose man made diamonds over the mined ones. And, they’ll pay less money and get a larger stone too.

But I predict manufactured diamonds will be to mined diamonds what Tudor is to Rolex or what Acura and Lexus are to BMW and Mercedes a quality alternative with a comparable look and feel, but cheaper, less valuable and ultimately less desirable.

Time will tell.

Pandora to Slash Nearly 400 Jobs

Pandora jewellery

Pandora plans to lay off 397 employees after disappointing second quarter results and a weakened outlook for the rest of the year.

While sales grew 4% in local currencies to $748.2 million (DKK 4.82 billion) for the quarter, the retailer lowered its revenue guidance for the year to an increase of 4% to 7%, from its previous forecast of 7% to 10%. It also expects lower profit margins, after that measure declined in the second quarter, it said Monday. The company’s stock price was down 21% at press time Tuesday.

Streamlining the business will help Pandora’s financial performance by reducing complexity and shifting resources to strategic priorities such as digital and e-commerce sales, CEO Anders Colding Friis explained in a separate statement Tuesday. Pandora has nearly doubled in size in the past three years, with new organizational practices emerging in different parts of the company, the executive added. The changes will reduce costs by about $23.3 million (DKK 150 million) per year, the company said.

“The adjustments are…necessary to protect our profitability,” Colding Friis said. “Sadly, the changes mean that good employees will lose their jobs, and we are supporting them in the best possible way.”

Of the layoffs, 218 will be in Thailand, where Pandora employs 13,000 people, including 5,000 at a new manufacturing center it unveiled in June. The company’s global workforce numbers 27,000.

Pandora has suffered from weak demand for its products in the US, as well as competition from unauthorized traders in the Asia Pacific region. Last month, it said it had reduced retail prices in China to combat the grey market, in which other companies sell its products without a license.

Meanwhile, Pandora has appointed Sid Keswani as president for the Americas. Keswani is a former CEO of grocery store chain Fiesta Mart, and replaces Scott Burger, who left the company in January. He will begin on August 13, reporting directly to the CEO.

Pandora will release its full results for the second quarter on August 9.

Lucapa Finds 3 More Special Diamonds at Mothae Mine

89 carat yellow stone from Mothae’s South East zone

Just a week after unearthing an 11.88 carat diamond, Lucapa Diamond Company has recovered more “special” diamonds from its Mothae mine, including a 28-carat stone and two light pink diamonds.

Special diamonds, a term the company uses to describe any diamond over 10.8 carats, have been abundant at Mothae in recent weeks.

The company is currently conducting ongoing bulk sampling, and recent results have included an 89 carat yellow stone from Mothae’s South East zone, a 25 carat yellow gem from the Neck zone and a 12-carat white diamond from the North zone.

The bulk sampling at the site is happening alongside construction of a new 150-tonne-per-hour commercial diamond plant, which is on schedule to be commissioned in H2 2018.

Lucapa Managing Director Stephen Wetherall has previously discussed the company’s bulk-sampling program, describing the prior lack of exploration at the site.

“Certain areas of the kimberlite pipe which hadn’t historically been sampled (Neck zone), or where there had been very limited historical testing (South-East and North zones), were thought to be underestimated as a result. At the time of acquisition, we believed there was much upside here and this program is designed to deliver that upside,” Wetherall said.

Wetherall also touched on the commercial diamond plant’s construction, and how the successful recovery results have given the company optimism for the road ahead.

“To have already recovered special sized diamonds from early sampling tonnages in all three of these areas gives us great confidence we can achieve this goal. It also adds to our excitement as we advance construction of our new 150 tph plant, which remains on track for commercial diamond production later this year,” he said.

The Mothae mine, located in Lesotho, South Africa, is a joint venture between Lucapa, which owns 70 percent, and the government of the Kingdom of Lesotho, which owns 30 percent.

Mouawad Group Buys 51.38 Carat Dynasty Diamond From ALROSA

51.38 Carat Dynasty Diamond

The Mouawad Group has acquired the 51.38 carat Dynasty diamond, the central diamond in a collection offered for sale by ALROSA.

The total revenue from the sale of the Dynasty collection amounted to about $10 million.

Fred and Pascal Mouawad, co-guardians of the jewelry firm, said: “We’re very proud of this important acquisition. We will add it to our repertoire of historic diamonds. What attracted us to the Dynasty is not only its exceptional quality but the transparency of its history and the fact it’s the largest and most valuable diamond ever sold by ALROSA. It’s a rare gem with a remarkable record.”

ALROSA sold the Dynasty diamond at a public auction on its electronic trading platform on August 2. The miner said that the Dynasty stone, a traditional round brilliant-cut diamond, D color, VVS1 clarity was the best quality large diamond ever manufactured in Russia, and also the most expensive stone ever sold by ALROSA.

The Dynasty collection consisted of five diamonds manufactured from a 179-carat rough diamond. It took a year and a half to create the collection which was manufactured by the firm’s cutting and polishing division.

ALROSA held the first auction for the sale of the collection last November where four of the five stones were sold with final prices coming in at about 30% over reserve prices on average, the miner said.

Blue diamonds may be blue because of where they are formed

Blue diamonds

Blue Diamonds are the world’s most expensive diamonds,  some stones worth tens of millions.

Why they are blue has long been know, But until now nobody has known how rare blue diamonds are made or where they come from.

Now scientists have discovered that they are formed 400 miles below the surface of the Earth, around four times the depth of cape series or white diamonds.

This is where the element boron can combine with carbon in such extreme pressure and heat that it crystallizes into the world’s most precious stone.

And because boron is mostly found on the Earth’s surface, scientists believe that it must have traveled down into the mantle when tectonic plates slipped beneath each other. Eventually volcanic action brought the diamonds up closer to the surface.

Blue Diamond is categorized as type IIb crystal and due to their extreme valuable, it is very rare to find one for scientific research purposes. An rare to find one that contains inclusions.

Gem Diamonds Recovers 101ct. Stone

Gem Diamonds 100.50 carat rough diamond

Gem Diamonds has unearthed a 100.50-carat diamond from its Letšeng mine in Lesotho, it said Friday.

The white, type IIa stone is the 11th over 100 carats the miner has recovered from the asset so far this year.

Gem Diamonds owns 70% of the Letšeng mine, with the state holding the remaining shares. The company also owns the Ghaghoo mine in Botswana, which it plans to sell.

Dubai Police recover $20 million diamond stolen from UAE-based company

blue diamond stolen

Police analysed thousands of hours of CCTV footage and questioned over 100 people to investigate the daring theft of a $20 million diamond from the vault of a Dubai based company.

Police were alerted about a robbery of a rare stone 9.33 carat after an unknown person broke through three security gates to get to the company’s vault on May 25. “The security system of the vault requires a group of employees to open the last gate simultaneously. Despite the precautionary measures, the suspect managed to steal the diamond.

In a major operation, Dubai Police recovered the diamond from Sri Lanka after it was smuggled out of the UAE in a shoe box by sea, an official said.

The suspect, a guard working with the money transfer company, was arrested in the UAE. After stealing the diamond, he gave it to a relative who smuggled the precious stone out of the UAE by hiding it in a sports shoe box, the police said.

The Asian suspect, who worked for the company. was arrested in a neighbouring emirate, had managed to break through three security gates to the vault to steal the diamond.

 

 

 

FTC Drops ‘Natural’ From Definition of Diamond, A Win for Lab-Grown Producers

DCLA can you tell the difference

In what can only be described as a victory for laboratory-grown diamond producers, the US Federal Trade Commission (FTC) has dropped the word ‘natural’ from its definition of a diamond, essentially redefining ‘diamond’ to include non-mined gemstones, as part its new guides for the jewelry industry. It further gives additional leeway to existing standards regarding the description of lab-grown diamonds (and metal alloys), and has dropped ‘synthetic’ as an appropriate descriptor of lab-grown diamonds except under certain circumstances. “The revision makes relatively far-reaching changes in what’s allowed as far as marketing lab-grown diamonds,” writes JCK’s Rob Bates, “and these changes almost entirely tilt toward the lab-grown sector.”

According to section § 23.12 of the Guides for the Jewelry, Precious Metals, and Pewter Industries, “Definition and misuse of the word ‘’diamond’,” the FTC writes: “A diamond is a mineral consisting essentially of pure carbon crystallized in the isometric system”, whereas it previously read “natural mineral”. “The Commision,” reads the Guide, “no longer defines a “diamond” by using the term “natural” because it is no longer accurate to define diamonds as “natural” when it is now possible to create products that have essentially the same optical, physical, and chemical properties as mined diamonds.” Later in the explanation of its changes, the commission describes why it sided with Diamond Foundry: “Diamond Foundry asked that the Commission remove “natural” from the diamond definition. It contended, “[t]he fact that diamonds exist in the soil of Earth” is “not a necessary attribute.” In its analysis, “The Commission agrees. The final Guides therefore eliminate the word “natural” from the diamond definition. When the Commission first used this definition in 1956, there was only one type of diamond product on the market – natural stones mined from the earth. Since then, technological advances have made it possible to create diamonds in a laboratory. These stones have essentially the same optical, physical, and chemical properties as mined diamonds. Thus, they are diamonds.”

‘Synthetic’ no longer recommended

In addition to this fundamental change to the definition of ‘diamond’, the FTC has opened the door to a much wider range of discriptors for lab-grown diamonds, provided they are not confusing for consumers. The Guides details its consideration of “cultured diamonds” according to the issues presented by the International Grown Diamond Association (IDMA) and Diamond Foundry on the one hand, and the Diamond Producers Association and Jewelers Vigilance Committee on the other. While the former did not get all it asked for (such as restricting the use of “ethical” or “conflict-free” diamonds to those from countries adhering to US labor standards), they tilted the balance in their favor. As Rob Bates points out, “In the past, the Guides listed the following approved descriptors for non-mined diamonds: laboratory-created, laboratory-grown, [manufacturer-name]-created, and synthetic. The new Guides still recommend the first three descriptions – though they no longer include synthetic. They also say that manufacturers can use other phrases if those terms “clearly and conspicuously convey that the product is not a mined stone.” And while adjectives such as created, grown and foundry are not recommended as descriptors, the commission says if the “suggested terms could be used non-deceptively in context (e.g., as part of an ad highlighting that the product is man-made), there is nothing to prevent marketers from doing so.”

As for using the word “cultured” to describe non-mined stones, the commission said it should be qualified, as the term on its own often leads consumers to believe a diamond is mined. The commission suggests marketers use words such as “man-made,” “lab-grown” or “foundry” to qualify “cultured,” thereby avoiding confusion about a diamond’s origins. However, marketers should not use the word “synthetic” to qualify “cultured,” the FTC noted, as it creates confusion among consumers, who believe the term indicates a stone is fake or artificial. Yet the commission goes even a step further in loosening its guidance on the use of ‘cultured’: While it still recommends against using the term cultured on its own, it now says that cultured can be used even if not immediately preceded by one of the approved descriptors.

Several commenters cited in the report, however, stated that the commission’s proposed guidance is inconsistent with international standards, which ban even the qualified use of “cultured” to describe synthetic diamonds. For example, a standard adopted by the International Organization for Standardization (ISO) in 2015 prohibits using “cultured” and “cultivated” to describe synthetic diamonds, and requires sellers to describe such products as “synthetic,” “laboratory-grown,” or “laboratory-created.” The JVC contended that the purpose of the ISO standard is “fully aligned” with the FTC Jewelry Guides. The fact that the FTC decided otherwise points to a rift between the new American standards and international ISO standards (a not uncommon rift nowadays). While the FTC removed ‘synthetic’ from its suggested descriptors, it declined to prohibit its use (another request by diamond growers), arguing that the term is not deceptive in every instance. But it did rule that it is misleading to use the term synthetic to “suggest a competitor’s lab-grown diamond is not an actual diamond.”

The changes, approved unanimously by the five-member commission, cap a six-year process of revamping the much-talked-about standards for marketing jewelry and gems. This revision marks the Guides’ first major overhaul in 22 years.

WFDB RESPONDS TO REVISED FEDERAL TRADE COMMISSION GUIDELINES

The World Federation of Diamond Bourses (WFDB) has responded to the revised U.S. Federal Trade Commission’s (FTC) guidelines released last week as they relate to the issue of descriptors for diamonds. The new guidelines are not in line with the Diamond Terminology Guidelines as agreed last year and implemented by the WFDB, the International Diamond Council, the International Diamond Manufacturers Association and CIBJO, the World Jewellery Confederation, said WFDB President Ernie Blom. However, he pointed out that the new guides do require that all lab-grown diamonds must be clearly and conspicuously disclosed.

“We have a united stand regarding nomenclature which was agreed with all the combined knowledge and experience of the leading industry bodies, but the FTC appears to have moved in a different direction,” Blom said.

Previously, the FTC’s guidelines approved non-mined diamonds: laboratory-created, laboratory-grown, [manufacturer-name]-created, and synthetic as descriptors, and while the first three remain, it has removed the term synthetic. “We feel that these changes provide too much of a bias towards the lab-grown diamond sector,” said Blom. “We appreciate the hard work of the FTC, but we do not feel that the views of the diamond sector were taken sufficiently into account, though we acknowledge there was consultation with American industry bodies. The guidelines do not include the views of the global diamond trade which the WFDB represents, although we are pleased that lab-grown stones have to be clearly marked as such.

“Our paramount aim is always consumer confidence and the revision has the potential to cause a degree of confusion. The FTC notes that manufacturers that make diamonds in a factory setting are free to use other descriptors as long as they ‘clearly and conspicuously convey that the product is not a mined stone,’ but we feel that this might provide too much latitude in their marketing claims.

“We appreciate that the FTC rejected a bid by diamond growers to include terms such as [manufacturer-name]-grown, foundry, created, and grown. These are stones created to order in a factory. We are also pleased that the FTC makes clear that any descriptors for non-mined diamonds must be absolutely clear and prominently displayed to consumers. A diamond sold without any descriptors must be a natural diamond.

“We hope that the door is still open for us to go back and approach the FTC in order to try and persuade the organization to re-think its decision,” Blom added.
