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.”

De Beers Sale Could Take 18 Months To Clear Regulatory Hurdles: Duncan Wanblad
The strategic divestment of De Beers highlights the persistent friction between corporate portfolio optimization and multi-jurisdictional regulatory compliance.
The long-awaited sale of De Beers could easily take 18 months to clear regulatory hurdles, says Duncan Wanblad, CEO of parent company Anglo American, once a deal is finally agreed.
Wanblad has, however, insisted that the company is not exclusive with any consortium and that more than one group remains involved in the process.
The strategic divestment of De Beers by Anglo American highlights the persistent friction between corporate portfolio optimization and multi-jurisdictional regulatory compliance.
Initiated in May 2024 as part of a sweeping restructuring, Anglo’s decision to offload its loss-making diamond unit was designed to sharpen capital allocation around core, high-margin assets like copper and iron ore.
However, CEO Duncan Wanblad’s candid assessment underscores a critical transactional reality: securing a signed agreement is merely the precursor to a prolonged regulatory clearance phase.
While Anglo American maintains a target to agree on deal terms by the end of 2026, market expectations regarding transaction completion require re-calibration. Antitrust approvals across key diamond consumption and trading hubs—most notably the United States, China, and the European Union—could extend the execution window by up to 18 months post-signing.
Given De Beers’ historical market concentration and influence across global supply chains, international competition authorities will undoubtedly subject any structural change in ownership to intense scrutiny.
Although the Global Diamond Consortium, spearheaded by former De Beers managing director Gareth Penny, has positioned itself as a primary contender, Anglo American has deliberately avoided granting exclusivity. While maintaining multiple bidding tracks preserves commercial leverage, it delays the precise regulatory preparation required for closing. Formal filings cannot be finalized until the specific jurisdictional footprint and capital background of the acquiring consortium are locked in.
