Debswana Diamond Company (Pty) Ltd is a partnership between the Government of the Republic of Botswana and De Beers. The company is engaged in diamond mining.

Debswana is the world's leading diamond producer by value and has played a significant role in the transformation of Botswana’s economy that it was. It is the largest non-government employer and the largest earner of foreign exchange in Botswana. 

The Diamond mines owned and operated by Debswana are:
Orapa diamond mine, opened in 1971 
Letlhakane diamond mine, opened in 1975 
Jwaneng diamond mine, opened in 1982 
Damtshaa diamond mine, opened in 2002 
Debswana also operates a coal mine named Morupule Colliery, opened in 1973. 

Sorting and valuation of the diamonds produced by these operations is undertaken at the Botswana Diamond Valuing Company (BDVC), a wholly owned subsidiary of Debswana, in Gaborone.
In addition to sorting and valuing Debswana’s production, the purpose of DTC Botswana is to make aggregated diamonds available for sale in Botswana for local manufacturing. This will support the GRB’s economic imperative to drive job and value creation from the country’s diamond resources.  

The company produces over 70% of the country’s export earnings, 30% of Gross Domestic Product (GDP) and 50% of government revenue.
