The Jwaneng diamond mine is the richest diamond mine in the world, and also the second largest in the world. It is nicknamed "the Prince of Mines", and is located in south-central Botswana about 170 kilometers (110 mi) southwest of the city of Gaborone.
Jwaneng means "a place of gems", and the Jwaneng mine means "where a small stone is found" in Setswana. The mine is owned by Debswana, a joint venture between De Beers and the government of Botswana. It commenced operations in 1982.
The mine owns and operates the local Jwaneng Mine Hospital, Acacia Primary School, and Jwaneng Airport. The mine maintains an ISO 14001 certificate for environmental compliance, being the first mine in Botswana to achieve this certification in 2000.
