South African billionaire Johann Rupert could play a significant role in the future of the global diamond industry if his luxury group, Richemont, joins a consortium bidding for De Beers, one of the world’s most recognised diamond producers.
The Swiss-based luxury company is reportedly discussing joining the Global Diamond Consortium, led by former De Beers chief executive Gareth Penny. The consortium is seeking to acquire Anglo American’s 85% stake in De Beers, with the diamond business valued at approximately $1 billion.
Why Is Richemont Interested?
Richemont owns prestigious jewellery brands, including Cartier and Van Cleef & Arpels. Joining the bid could give the company greater influence over its natural diamond supply chain, helping secure access to the stones used in its luxury jewellery collections.
The potential investment comes at a difficult time for the diamond industry, which has faced declining prices, weaker demand in China and growing competition from cheaper laboratory-grown diamonds.
De Beers has also experienced significant financial pressure. In 2025, the company reported an underlying operating loss of $787 million, despite generating nearly $3.5 billion in revenue.
What Could This Mean For South Africa?
A possible change in ownership could have implications for South Africa and other diamond-producing countries, where mining supports employment, local businesses and economic activity.
De Beers operates across several countries, including South Africa, Botswana, Namibia, Angola and Canada. A stronger investment structure could potentially help stabilise its operations and support the long-term demand for natural diamonds. However, the impact on jobs, production and local communities will depend on the final ownership arrangements and future business decisions.
Botswana, which already owns 15% of De Beers, also has a significant role in the process because of its rights concerning the proposed sale. Its participation could influence the final structure of any deal.
Although negotiations involving Richemont are reportedly advanced, the company has not confirmed that it will join the consortium. American jewellery retailer Signet has also been linked to discussions about joining the group.
If the deal proceeds, it could strengthen the connection between luxury jewellery brands and diamond producers at a time when the natural diamond market is under pressure.
For now, the industry will be watching closely to see whether Rupert’s Richemont takes the next step and whether the proposed acquisition can help restore confidence in natural diamonds.
