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.”

- Retail Proliferation: Accelerating the strategic rollout of a comprehensive pan-India retail footprint to capture domestic market share.
In a pivot toward high-margin industrial applications, DLGD is leveraging its proprietary synthesis capabilities to produce high-precision single-crystal diamonds. This initiative positions the firm as a critical component supplier for cutting-edge sectors, including:
- Quantum Computing & Semiconductors: Utilizing diamond’s superior thermal conductivity and electronic properties.
- Defense & Optics: Engineering specialized materials for high-stress aerospace and optical environments.
- Thermal Management: Providing heat-dissipation solutions for next-generation hardware.
