De Beers sale  will involve  Botswana plus one or two buyers

Published

on

Anglo American is fast-tracking the sale of its crown jewel, De Beers, in an unusually streamlined process that skips the traditional two-round bidding. Instead, the mining giant will move forward with just “one or two” shortlisted buyers — in close coordination with the government of Botswana, its long-time diamond partner. Anglo American is expected to raise $3bn to $4bn from the sale of its 85 per cent stake in the loss-making diamond miner. The remaining 15 per cent is owned by the government of Botswana, which wants to secure a majority holding, 

Among those vying for a piece of the diamond major are some familiar industry names. Angola’s state-owned Endiama has proposed a pan-African partnership spanning Botswana, Namibia, and South Africa. Speculation also swirls around potential bids from Qatari and Gulf investors.

Anglo will hold direct talks with selected bidders alongside Botswana, which owns 15% of De Beers through its Debswana joint venture. Wanblad said he expects the sale process to conclude within six months but did not rule out spinning off De Beers if negotiations fail.

The government’s participation marks a shift in tone after President Duma Boko criticized Anglo’s handling of De Beers and said his administration could run it more effectively. De Beers swung to a $189 million loss in the first half of 2025 from a $300 million profit a year earlier amid weak diamond prices, adding pressure for a deal.

Anglo values De Beers at about $5 billion, though analysts at UBS estimate the sale could generate between $3 billion and $4 billion, including deferred payments, given challenging market conditions.

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.
