Answer: Botswana
Notes: The Jwaneng Diamond Mine in Botswana is currently the richest diamond mine in the world, with an estimated value of 1 billion euros. It is famously known as the 'Prince of Mines' and is located near the edge of the Kalahari Desert. The mine lies in an ancient volcanic crater about 170 kilometers southwest of Botswana's capital, Gaborone. It is operated by Debswana, a joint venture between De Beers, a leading global diamond company, and the Government of Botswana. Jwaneng means "a place of gems" in the Setswana language. The mine sits on a kimberlite pipe, a volcanic formation that brings diamonds from deep inside the Earth to the surface. The site was discovered by De Beers in the 1970s and has been in operation since 1982. The recent highlight of its value and global importance makes it a key player in the international diamond industry.
