"Diamond mine" redirects here. For other uses, see Diamond mine (disambiguation).

Small rough diamonds from Russia. Crystals are about 0.7 to 0.9 mm in size.
There are a limited number of commercially viable diamond mines currently operating in the world, with the 50 largest mines accounting for approximately 90% of global supply.[1] Diamonds are also mined alluvially over disperse areas, where diamonds have been eroded out of the ground, deposited, and concentrated by water or weather action. There is also at least one example of a heritage diamond mine
