The Jwaneng Diamond Mine in Botswana is the richest diamond mine in the world, with an annual output of as much as 15.6 million carats. Mine richness takes into account the rate of diamond extraction combined with quality of the diamonds that are mined, by sale price per weight. To extract the diamonds, the facility produces 9.3 million tons of ore and an additional 37 million tons of waste rock per year.
