‘As we go independent, we have the freedom to focus on marketing as hard as we focused on mining’

IT has only been three years since Al Cook took over as CEO of De Beers, but he could well be out of a job soon. That’s not of his own doing but the result of Anglo American’s determination to concentrate primarily on copper and iron ore. Consequently, its 85% stake in De Beers has been put up for sale and Cook’s job may well be on the line once the process has been completed. Before then, he must juggle a few balls to make this a successful process.

For one, Anglo values the stake at close to $5bn, whereas the sell-side consensus is below $3bn against the backdrop of a severely depressed diamond market. Secondly, the buyers are not likely to be global multinationals but a mix of sovereign funds and African governments. Both Angola and Botswana have announced their interest, with the latter the clear frontrunner as it owns 15% of De Beers and supplies 70% of its annual rough diamond output. In February 2025, De Beers and Botswana also extended their 10-year sales agreement and a 25-year mining licence extension for the 50:50 Debswana mining joint venture.

And finally, Cook has to improve the valuation by addressing some of the company’s key operations issues: De Beers needs to continue reducing its diamond stockpile, estimated to be as much as $2bn last year, deal with the decline in rough diamond prices – down again in 2025 – and address a surge in demand for cheaper, lab-grown gems.
