De Beers Issues Synthetics Guidelines

De Beers has provided its rough-diamond clients and Forevermark partners with guidelines on how to operate in the lab-grown market if they wish to continue tapping into its branding.

The mining company, which in 2018 forayed into gem-quality synthetics with the launch of its Lightbox brand, is demanding businesses make full disclosure about their product, segregate synthetics from their natural supply, and do not make unproven claims about either category. The “Statement of Principles” outlines the legal structures companies with lab-grown diamond units must have if they wish to use the sightholder logo, as well as the procedures and training they are required to implement to avoid contamination or misleading marketing.

While De Beers already had rules mandating disclosure and other best practices, the new principles “ensure there is no room for doubt” about how clients may use the sightholder logo, explained David Johnson, head of strategic communications for De Beers. Some of the rules form part of De Beers’ contract with clients, allowing the miner to penalize those who flout them, while others are only recommendations.

“We believe the principles within the document set out a responsible approach, and that they are important for ensuring people can make clear and informed choices about what they are buying,” Johnson added.

The document refers to lab-grown diamonds as “artificial” products that “do not have the same inherent, naturally occurring characteristics or enduring value” as natural diamonds. The miner continues to define diamonds as a natural mineral in line with the International Organization for Standardization (ISO).

De Beers sent the guidelines to clients earlier this month, as numerous sightholders have launched lab-grown businesses under separate entities and trading names.
The following is a summary of the guidelines:

  • De Beers customers may only use the sightholder license — including displaying the sightholder logo — for business entities that are exclusively natural-diamond businesses. Entities with both natural and lab-grown activities may not use the logo.
  • The miner recommends setting up distinct and independent businesses for any lab-grown diamond activities, with separate systems, processes and workforces.
  • The rules prohibit “false, misleading or unsubstantiated” claims about the enduring value of lab-grown diamonds, whether directed at other businesses or at consumers. They cannot state or imply that lab-grown diamonds have the “identical inherent value characteristics” as natural diamonds.
  • Similarly, unproven claims about the environmental benefits or ethical advantage of lab-grown diamonds over natural ones are forbidden.
  • Sellers must provide the buyer with full and unambiguous disclosure before the transaction is complete.
  • They’re also required to ensure segregation at all stages of the supply process, such as storage, cutting and polishing, packaging, and transportation. Ideally, suppliers should handle natural and lab-grown stones in separate sites.
  • De Beers customers must “take steps” to ensure full disclosure and segregation further along the supply chain, down to the consumer.
  • Clients must have protocols to identify and mitigate contamination risks, and train staff members on the “operational, commercial and reputational impacts” of lab-grown diamonds.
  • Preferably, companies should disclose the countries in which the synthetic diamond was grown, polished and made into jewelry, as well as the identity of the grower. De Beers says businesses should “strive” to declare this, though it’s not an absolute requirement.
  • Grading language must contain words that make it clear a stone is lab-grown.
  • Customers must follow relevant laws, regulations and best practices, such as the standards that the US Federal Trade Commission (FTC) and the ISO have published.

De Beers rough diamond sight grows to $575m

De Beers rough diamond

Anglo American’s De Beers the world’s largest rough diamond producer by value, sold $575 million worth of rough diamonds at the fifth sight of this year.

The value is a 6% increase from the $541m sight in the same period last year and 3.7% higher than the $554m sight last month.

De Beers has increased efforts in recent months to find a way to verify the source of diamonds and ensure they are not from conflict area where rough diamonds may have been used to finance violence.

Last month De beers announced it would start selling jewellery made with laboratory grown diamonds.

9ct. Synthetic Sets ‘World Record’

9 Carat Lab Grown Diamond

WD Laboratory Grown Diamonds has created what it claims to be the world’s largest known synthetic diamond made using chemical vapor deposition (CVD).

The ideal cut, round brilliant  9.04 carat, VS2 clarity stone broke the synthetic diamond producer’s own previous world record of 6 carats, the company said last week.

“No other CVD diamond manufacturer has come close to this size and quality,” Clive Hill, its founder and chairman, claimed. “But this is not an easy task, and we overcame significant hurdles that we’ll undoubtedly face and overcome again.”

WD Lab Grown Diamonds intends to work on producing even larger CVD synthetics, Hill added.

Labs Refute Claims HPHT Escaping Detection

IIDGR AMS2 synthetic diamonds test

Major gemological laboratories have rebuffed claims that detection machines are failing to spot synthetic diamonds that have undergone irradiation.

In a trade alert last week, Diamond Services argued that the treatment, generally used to alter the color of a stone, can mask the phosphorescence effect when diamonds created using High Pressure-High Temperature (HPHT) undergo scanning at room temperature.

While detection machines can often identify HPHT diamonds because they phosphoresce — or glow — under ultra-violet light, certain devices fail to spot some of those stones that have been subject to irradiation, the Hong Kong-based diamond-technology company argued.

However, De Beers and the Gemological Institute of America (GIA) have denied the impact of such a phenomenon on their machines’ ability to sift out HPHT synthetics.

“The International Institute of Diamond Grading and Research (IIDGR) confirms that its instruments AMS2, SYNTHdetect, DiamondView and DiamondSure are all effective at screening HPHT synthetic material which has been irradiated and is tested at room temperature,” the De Beers-owned grading unit said in a statement last week.

“Any business using these devices can have full confidence that any such material will be detected without the need to undertake tests at different temperatures,” it added.

Meanwhile, although detection devices based on phosphorescence may not be able to detect some HPHT-grown irradiated synthetics, the GIA’s machines can spot them, the Carlsbad, California-headquartered laboratory stressed.

“The ability of the instruments that GIA uses to differentiate natural diamonds from HPHT and CVD [chemical vapor deposition]-grown synthetic diamonds, including the GIA iD100 gem-testing device and the GIA Melee Analysis Service, is not affected by irradiation treatment,” the GIA told Rapaport News.

Examining diamonds at the temperature of liquid nitrogen can be an extremely accurate method of detecting synthetics, while a technique called Raman spectroscopy is a simple way of spotting irradiated diamonds, according to Joseph Kuzi, founder and president of Diamond Services.

“Our latest findings indicate that the diamond and jewelry trades should show extra caution, but we do not claim that irradiated HPHT-grown synthetic diamonds are undetectable,” Kuzi said.
