Anglo American may continue to control De Beers for up to 18 months after agreeing a sale, as the transaction could require regulatory clearance in the US, China and Europe, according to Anglo American chief executive Duncan Wanblad. Botswana, which owns 15% of De Beers, also holds pre-emption rights that could affect the timetable. Anglo is seeking to sell its 85% stake in the diamond producer as part of a restructuring announced in May 2024. The mining group is also working towards a merger with Canada’s Teck Resources to form Anglo Teck. Buyer Identity Will Determine Approvals Wanblad said the…

Sarine Technologies reported a 6% decline in group revenue to US$14.4 million for the six months ended 30 June 2026, as lower revenue from capital equipment and Galaxy scanning services offset growth in its newer recurring businesses. The diamond technology company said continued competition from lab-grown diamonds (LGDs), alongside lower rough natural diamond supply, remained challenging for the natural diamond manufacturing sector. However, larger and higher-quality natural diamonds, which account for a substantial share of Sarine’s recurring revenue, have been less affected by LGD competition. New Services Grow Sarine’s Most Valuable Plan (MVP), its cloud-based solution for planning and optimising…

Researchers have identified a 6.87-carat CVD synthetic diamond fashioned to resemble a rough natural diamond crystal, in what they said was the first reported case of its kind. The near-colourless stone, measuring approximately 11mm across, was examined by Nick Davies, Sema Firat, David Fisher and Thoufieq Shaik of De Beers Science & Technology. Their findings were published in the Spring 2026 edition of the Gemological Institute of America’s Gems & Gemology journal. Surface Examination Reveals Differences The stone had a near-octahedral outline similar to the crystal form of some natural rough diamonds. Examination showed that it was not a genuine…

A ring purchased for £5 at a car boot sale has been identified as a 3.02 ct natural diamond set in 18 ct gold with an estimated value of £15,000 following an appraisal at a jewellery valuation event in Oxfordshire.

The CIBJO Diamond Commission has proposed that the 4Cs grading system should be used exclusively for natural diamonds and that “synthetic” should become the preferred term for diamonds produced through industrial processes. The proposal is contained in the fourth pre-Congress Special Report ahead of the 2026 CIBJO Congress, scheduled to take place in Vicenza, Italy, from September 4. The report was prepared by the Diamond Commission, headed by Udi Sheintal. Proposed Change to Terminology The report calls for CIBJO to reconsider its terminology for synthetic diamonds, with “synthetic” proposed as the preferred term rather than “laboratory-grown” or “laboratory-created”.
