Where Is the World's Largest Diamond Mine?

The Orapa diamond mine in north-central Botswana, operated by Debswana (a partnership between De Beers and the Botswanan government), is the largest diamond mine by area, with its open pit covering about 1.18 square kilometres. It produces roughly 10–12 million carats annually. Botswana's diamond industry accounts for about 20 % of the country's GDP and has helped transform it from one of the poorest nations at independence in 1966 to an upper-middle-income country. The Jwaneng mine, also in Botswana, is the richest by value.
