Botswana
Botswana is among the world’s most important diamond producers by value. The large Orapa and Jwaneng mines were developed from the late 1960s; diamonds have since been a mainstay of the country’s economy.
Stones
Botswana mainly yields colourless diamonds of all sizes, including very large rough stones time and again.
