De Beers and Botswana Reach Agreement on New Rough-Sales Deal and Extended Mining Licenses

De Beers and the government of Botswana have officially concluded their negotiations, finalizing a new rough diamond sales agreement and securing an extension of mining licenses for their joint venture, Debswana.

This marks the successful end to a long negotiation process that has seen multiple extensions of the previous contract since it expired in 2021. Despite reaching an agreement in principle in June 2023 and signing a “heads of terms” document in September, the deal remained pending due to discussions with Botswana’s former president, Mokgweetsi Masisi, and was finalized after Duma Boko assumed the presidency in November.

Under the new sales agreement, 30% of Debswana’s production will be allocated to Okavango Diamond Company (ODC), Botswana’s state-owned trading arm, with plans to gradually increase this to 50% over the next 10 years. The deal also includes a significant extension of Debswana’s mining licenses, which were initially set to expire in 2029. A 25-year extension of these licenses is part of the agreement, further solidifying the long-term future of diamond mining in the country. Additionally, the partners will jointly handle the sale of exceptional diamonds, sharing in the profits of polished sales.

Furthermore, the new agreement involves a BWP 1 billion ($75 million) upfront investment by De Beers in a diamond development fund, with additional contributions over the next decade. The fund aims to diversify Botswana’s economy, create jobs, enhance local diamond beneficiation, and provide training opportunities. This move is part of a broader strategy to ensure that the country’s diamond sector continues to contribute to economic growth and development for years to come.

CVD Synthetic Fashioned To Imitate A Rough Natural Diamond

The Near-Colorless Stone Is Believed To Be The First Time Creators Of A Synthetic Chemical Vapor Deposition (CVD) Diamond Have Shaped It To Resemble A Rough Diamond

The 6.87-carat near-colorless CVD diamond was shaped to resemble a natural rough octahedral crystal but showed distinct synthetic features under microscopic and spectroscopic analysis.GIA’s tests confirmed the stone’s synthetic origin, noting polishing marks, facet junction roughness, and luminescence patterns inconsistent with natural diamonds.

No evidence currently suggests widespread substitution of synthetics for rough natural diamonds, but existing detection tools could be adapted if such cases increase.

The near-colorless stone is believed to be the first time creators of a synthetic chemical vapor deposition (CVD) diamond have shaped it to resemble a rough diamond, according to an article in the spring issue of the institute’s Gems & Gemology quarterly journal.

Upon investigation with the use of raman spectroscopy, the results confirmed that the material was a diamond, with its near-octahedral shape similar to that of a natural rough crystal. Further analysis showed that it was not a true octahedron, as only one set of opposing faces was parallel. Microscopic observation under differential interference contrast revealed extremely flat faces marked mainly by parallel polishing lines, unlike the growth steps and trigons typically seen on natural octahedral faces. The facet junctions were extremely rough, possibly due to measures taken to improve the color, after which the main faces appear to have been repolished, the institute explained.
