De Beers Group has introduced its DiamondProof device at select retail stores, offering rapid and reliable verification of natural diamonds.
The device distinguishes natural diamonds from lab-grown alternatives and simulants by detecting unique chemical signatures, the company announced Monday.
Already in use by major jewelry retailers, DiamondProof debuted in the U.S. following its unveiling at the JCK show in Las Vegas last June.
Designed for use at retail counters and back offices, the device delivers instant results on a digital screen, ensuring a 0% false positive rate—meaning lab-grown diamonds are never misidentified as natural.
By clearly differentiating between natural and synthetic stones, DiamondProof enhances consumer confidence and helps retailers educate customers.
“Natural diamonds and lab-grown diamonds are fundamentally different products,” said De Beers Brands CEO Sandrine Conseiller. “Consumers should have confidence in such a meaningful purchase, and DiamondProof gives retailers the ability to offer them greater peace of mind.”
Early adopters include some of the largest U.S. jewelry retailers, with independent stores set to carry the device soon.
De Beers has also established after-sales support in the U.S. and plans to scale up production next year to meet rising demand.
“By rapidly and reliably identifying natural diamonds, DiamondProof will be essential in strengthening customer confidence,” added Sarandos Gouvelis, De Beers’ senior vice president of pricing, product, and technology development. “Having the device in retail settings will empower consumers to make informed decisions.”
