De Beers launches DiamondProof; distinguishes naturals from LGDs within seconds
De Beers has launched a diamond verification device aimed specifically at retailers. DiamondProof distinguishes natural gems from LGD in store within seconds as the customer looks on. DiamondProof distinguishes between the chemical composition of natural diamonds and LGD. De Beers says fewer than 1 per cent of diamonds will need additional evaluation and it guarantees that no synthetic diamonds will be mistakenly identified as natural.
De Beers Group announced that its innovative retail-facing diamond verification device, DiamondProof, has landed in select retail stores for the first time, giving consumers the ability to witness just how quickly the device can distinguish natural diamonds from non-natural diamonds, such as laboratory-grown diamonds (LGDs) and diamond simulants, providing a tool for retailers to help educate their customers on the differences between natural diamonds and other products. With research showing that almost half of consumers are unaware that LGDs can be readily detected, this easy-to-use device will enable retailers to show their customers just how quickly natural diamonds can be identified.
The first DiamondProof prototype instrument was unveiled at the JCK show in Las Vegas in June 2024 and has been developed to rapidly and easily screen both loose diamonds and those set in jewellery. With a zero percent ‘false positive rate*,’ the device will never mistake a lab-grown diamond as a natural diamond and delivers results within seconds.
Sandrine Conseiller, CEO of De Beers Brands, said: “Natural diamonds and LGDs are two fundamentally different products. Natural diamonds are rare, one-of-a-kind miracles of nature that come to us from the earth through heat, pressure and time. This incredible journey is what makes them the ultimate marker of life’s most profound emotional moments. Consumers should be able to have confidence in such a meaningful purchase, and DiamondProof allows retailers to offer them greater peace of mind. We are in a new era of transparency at retail, and customers deserve to know what they are buying.”

Richemont and Signet Jewelers Could Join Global Diamond Consortium In Bid For De Beers
Richemont, Signet Would Connect The Consortium To Key Global Growth Vectors Spanning Luxury High Jewelry and Mass-Market Retail.
The Global Diamond Consortium (GDC)
Richemont and Signet Jewelers are reported to be in talks about joining the Global Diamond Consortium (GDC), the preferred bidder for De Beers according to a Bloomberg News report.
GDC was selected in July 2026 as one of Anglo American’s preferred bidders for De Beers as part of Anglo American’s ongoing corporate restructuring.
The potential inclusion of Richemont—owner of luxury Maisons including Cartier and Van Cleef & Arpels—and Signet Jewelers—the world’s largest retailer of diamond jewelry, operating brands such as Kay Jewelers, Zales, and Jared—would connect the consortium to key global growth vectors spanning luxury high jewelry and mass-market retail.
Strengthening the Natural Diamond Ecosystem: Participation by major luxury brands and global retail leaders reinforces commitment across the entire value chain—from responsible mining and manufacturing to consumer engagement.
Balanced Governance Structure: Discussions center on potential minority equity positions that would support long-term category growth while maintaining appropriate separation between ownership and commercial strategy.
Broad Stakeholder Participation: The consortium continues to advance talks with host governments, including discussions with the Government of Botswana regarding a potential increase in its equity share in De Beers from 15% to approximately 25%, alongside participation from private investors and southern African host nations.
Discussions between GDC, Richemont, Signet, and participating government stakeholders remain ongoing. Terms of any potential participation, including the size of equity interests, have not been finalized and remain subject to regulatory approvals and definitive documentation.
