De Beers Sees 38% Surge in Q3 Diamond Output Driven by Botswana Operations

De Beers announced a 38% year-on-year increase in rough diamond production for the third quarter of 2025, totalling 7.7 million carats. The growth was largely powered by higher output from Botswana, which delivered 6.0 million carats — a 51% rise — as the Jwaneng mine operated at full capacity and processed richer ore ahead of scheduled maintenance later in the year.

Output in South Africa held steady at 0.7 million carats as the Venetia mine continued its shift to underground mining, while Namibia’s production remained unchanged at around 457,000 carats. Conversely, Canadian operations saw a 15% dip to 0.5 million carats, reflecting the mining of lower-grade ore.

In terms of sales, De Beers moved 5.7 million carats of rough stones during the quarter, generating a provisional revenue of approximately $700 million — a substantial rise from the same period last year. The company noted that while trading conditions for rough diamonds remain tight globally, consumer appetite for natural diamond jewellery in the United States continues to hold firm.

De Beers has reaffirmed its full-year production outlook at between 20 and 23 million carats, maintaining an average unit cost of around $94 per carat.
