Debswana

A 50:50 joint venture between the government of Botswana and De Beers, formed in 1969, and the world's leading diamond producer by value. Diamonds account for roughly a third of Botswana's fiscal revenue, so Debswana's output decisions carry national economic weight.

Debswana operates four diamond mines in central and eastern Botswana, including Jwaneng, often described as the world's richest diamond mine, and Orapa. Production was cut to about 15 million carats in 2025 in response to weak demand, and the company plans to raise output to 18 million carats in 2026. It is also seeking about $6bn to take Jwaneng underground.
