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.”

ALROSA Indicates Mir-Deep Project Could Commence As Early As Next Year
The Project Is Viewed As Strategically Significant Given The Historic Contribution Of The Mir Asset To ALROSA’s Production Portfolio
ALROSA has indicated that development activity at the proposed Mir-Deep project could commencece as early as next year, positioning the asset as the long-term successor to the original Mir Mine operation, which was permanently shut following the fatal 2017 flooding incident that resulted in eight casualties.
The company stated that it is prepared to accelerate execution of the construction phase of the Mir-Deep project—estimated in 2024 at an investment outlay exceeding US$1.5 billion—subject to favorable macroeconomic conditions and a reduction in borrowing costs. The development reflects ALROSA’s broader strategy to restore high-volume production capacity while optimizing capital deployment amid evolving financing conditions.
Mir-Deep is planned at the same site as the historic Mir mine in eastern Siberia and will involve the sinking of new shafts to access deeper diamond-bearing reserves located below the previous accident zone, within the same geological structure. The project is viewed as strategically significant given the historic contribution of the Mir asset to ALROSA’s production portfolio. Prior to its closure, the mine was producing approximately 3.8 million carats annually, representing nearly 10% of the company’s total output.
Originally commissioned in 1957 as the first diamond mine in the former USSR, the Mir operation remains one of Russia’s most iconic diamond assets. The 2017 flooding disaster resulted in extensive destruction of underground infrastructure, mining workings, and equipment, leading to the suspension of operations.
In an operational update issued on 28 April, Pavel Marinychev confirmed that preparatory activities initiated in 2023 had been completed and that Russia’s Main State Expert Review authority (Glavgosexpertiza) had approved the extraction of certain reserves within the project area.
Earlier resource assessments released in September 2023 estimated identified reserves at approximately 173.5 million carats. More recent evaluations by Russia’s State Commission on Reserves have reportedly increased the estimated resource base to nearly 200 million carats, further strengthening the project’s long-term economic potential and strategic relevance within the global diamond supply landscape.
