Botswana could buy De Beers outright, looks towards greater control of diamond sector
The government of Botswana could buy an additional stake in De Beers, or even acquire the business outright, according to a Financial Times (FT) report. Full control over De Beers would allow Botswana to capture a larger share of value across the diamond supply chain — from production to marketing and distribution.
The southern African nation’s government appointed the French investment bank as co-adviser, alongside Swiss boutique lender CBH Compagnie Bancaire Helvétique, regarding “the potential acquisition of all or part of the De Beers Group”. The news follows last week’s announcement that Botswana had secured a $12bn investment commitment from Qatar-based Al Mansour Holdings to help stabilize its faltering economy.
In July, Botswana’s mining minister Bogolo Kenewendo reaffirmed President Duma Boko’s determination to expand the country’s stake in De Beers, signaling a clear policy direction towards greater national control of the diamond sector.
Anglo American, which is looking to sell its stake in De Beers, received approximately nine indications of interest in first-round bids this month, the Financial Times reported, citing unidentified people familiar with the process.
The Botswanan government holds a significant position in the potential transaction as it has the right to match any third-party offer for the diamond company.This development comes as Anglo American continues its divestiture process for its De Beers ownership stake.

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.
