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…

Lucara Diamond Corporation has sold the 2,488-carat Motswedi diamond, recovered from its Karowe mine in Botswana, but has not disclosed the buyer, transaction value or intended use of the stone. The sale was confirmed in the Canadian miner’s second-quarter results, which reported revenue of $41 million for the three months ending 30 June 2026. Sale Included in Quarterly Revenue Lucara’s quarterly revenue declined by 6% from $43.7 million in the corresponding period of 2025.

The CIBJO Coloured Stone Commission has released its fifth pre-Congress Special Report ahead of the 2026 CIBJO Congress, which will take place in Vicenza, Italy, from September 4.

Users can also request precise design changes, such as moving a stone by 1.25mm or…

Pandora and the Natural Diamond Council (NDC) have publicly disagreed over the jeweller’s new carbon footprint disclosure initiative for lab-grown diamonds, with the NDC accusing the company of using misleading comparisons between lab-grown and natural stones. The dispute follows Pandora’s announcement that it will disclose the carbon emissions associated with every lab-grown diamond it sells, introducing what it describes as a “fifth C” alongside the traditional diamond grading criteria of cut, colour, clarity and carat. Pandora Introduces Carbon Footprint Disclosure Pandora said the new information will cover emissions generated throughout the production process, from the raw materials used to grow…
