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.”

Exceptional Platinum Jewelry Designs Win AGTA Spectrum Awards Competition
More than 60 platinum jewellery entries competed for top honours, recognising exceptional craftsmanship, innovative designs and the versatility of platinum across coloured gemstones and pearl jewellery.
Platinum Guild International (PGI), in partnership with the American Gem Trade Association (AGTA), is pleased to announce the Platinum Honors winners of the 2026 AGTA Spectrum Awards.
More than 60 platinum jewelry entries were submitted to the Platinum Honors category, which recognizes outstanding uses of platinum in colored gemstone and natural or cultured pearl jewelry across multiple categories, from Evening Wear to Engagement Rings. PGI also traditionally presents an award for Best Use of Platinum and Color.
The AGTA Spectrum Awards competition was held at the Omni Frisco Hotel at the Star in Dallas, where Jenny Luker, President, PGI USA, judged the Platinum Honors category.
“The AGTA Spectrum Awards bring together an extraordinary range of platinum jewelry, and the level of design innovation, technical execution, and artistry is exceptional,” said Luker. “It’s exciting to see so many talented designers exploring the material in different ways, creating intricate, distinctive pieces that showcase the versatility of platinum.”
AGTA CEO John W. Ford Sr. thanked PGI for its sponsorship of the Spectrum Awards and extended his congratulations to the Platinum Honors winners. “Receiving a Platinum Honors distinction from PGI is one of the industry’s highest achievements,” he said. “We were happy to see Platinum so well represented among the AGTA Spectrum entries, which increased by 21% this year.”
Platinum’s potential for design innovation and technical accomplishment was exemplified by several of this year’s AGTA Spectrum Award winners.
The Best of Show award and 1st Place in Classical Wear was awarded to “Can’t Look Away,” a necklace by Lezlie Slavens of Luxe Fine Jewelry and collaborators. The design features a carved Paraiba tourmaline backed in platinum, suspended from a diamond-accented platinum chain and illuminated by a magnet-activated LED light source.
The Art Deco-inspired “Horus Egyptian Revival” bracelet by Joseph Dardashti, in Platinum with Rubies, Sapphires, Emeralds, Diamonds, and Onyx, won 1st Place in the Spectrum Awards’ Evening Wear category and also received a Platinum Honors distinction in the same category.
Jeffrey Bilgore’s Mahenge Spinel and Diamond “Neuvelle Moi et Toi Forever” Platinum ring received the Stuller Color of the Year Award, a new category honoring exceptional interpretations of Stuller’s “Signature Red”, and won 2nd Place in the Spectrum Awards’ Classical category.
The honour of 1st Place in the Bridal category went to Niveet Nagpal of Omi Gems, Inc. for his Platinum ring featuring a 5.32 ct. Paraiba Tourmaline, accented by Tourmaline (1.05 ctw.) and Diamonds (0.69 ctw.).
New entrant Shelby Lichtenstein was awarded 1st Place in Engagement Rings with her Platinum “Something New, Something Blue” ring, featuring a 4.50 ct. blue emerald-cut Zircon accented by Diamonds (0.26 ctw.).
“Because of platinum’s durability, strength, and tensile properties, designers can achieve things that might not be possible with other metals,” said Luker. “Whether it’s intricate micro pavé work or delicate prongs, platinum allows for exceptional precision while ensuring that gemstones remain secure.”
Across all categories of the Spectrum Awards competition, noteworthy platinum jewelry trends included bezel settings in engagement rings, designs that paired platinum with moonstones for a dreamy, elegant white-on-white effect, and brooches for both men and women that incorporated multiple gemstone types in an array of cuts and sizes.
“The level of design this year was incredible,” said Luker. “I was particularly impressed by the innovation and execution. Platinum plays such a wonderful supporting role to gemstones, and that relationship has endured—and will endure—forever.”
