Botswana’s VP expresses confidence in ongoing efforts to secure a buyer for De Beers
Botswana’s Vice President Ndaba Gaolathe has expressed strong confidence in the ongoing efforts to secure a buyer for De Beers, as Anglo American prepares to divest from its diamond operations. His remarks, delivered during an interview in Washington, suggest that the process is progressing well and that there is broad international interest in acquiring Anglo’s 85 per cent stake in the iconic diamond company.
The sale comes amid Anglo American’s strategic pivot away from diamonds and other assets to concentrate on copper, a sector currently yielding higher returns. De Beers has seen its valuation decline sharply in recent years, with Anglo having written down its value twice in the past 13 months. Once a cornerstone of the group’s portfolio, De Beers is now valued at $4.1 billion, significantly lower than when Anglo assumed full control in 2012.
Crucially, Gaolathe indicated that Botswana — already holding a 15 per cent stake in De Beers — is considering a substantial increase in its ownership, potentially up to 50 per cent. Such a move would mark a major shift in the company’s ownership structure and could redefine the power dynamics within the global diamond industry. Botswana, as one of the world’s largest diamond producers, has long been a key partner in De Beers’ supply chain, and this increased stake would reinforce its strategic influence over the sector.
The government’s willingness to expand its stake also reflects a broader effort by resource-rich nations to assert greater control over their mineral wealth and to ensure that profits from extraction are more equitably shared. If realized, Botswana’s expanded role in De Beers could serve as a model for other producing countries seeking to balance economic development with stronger national participation in global value chains.
With a sale or IPO expected by the end of 2025, the coming months will be critical in shaping the future of one of the diamond industry’s most storied names. Will Botswana emerge as a dominant shareholder, or will another global player step in? Either way, the outcome is likely to reshape the contours of the international diamond trade.

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.
