There are a limited number of commercially available 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.

The lamproite diamond source is unusual, as almost all diamonds are mined from kimberlite formations and from alluvial deposits of diamonds weathered from that "hardrock" source. The most prominent lamproite diamond source is the Argyle diamond mine in Australia. It is notable that the physical characteristics of Australian lamproite and the ...
The Williamson diamond mine is a large open pit mine currently about 90 meters (300 ft) deep. Diamond mining operations at the Williamson diamond mine are composed of four distinct activities: mining of the pit, re-treatment of tailings to recover missed diamonds, and gravel mining both on the property and adjacent to the property where gravel has been alluvially deposited.
Later, diamond discoveries were made in the Soviet Union (now Russia). [2] Since the 1990s, major diamond discoveries were made and mining operations began. Canadian diamonds play a large role in the world market. [2] In 2019, Canadian mines produced 18.6 million carats of diamonds, valued at $2.25 billion. [3]
The discovery of diamond-bearing kimberlites in the 1870s in Kimberley sparked a diamond rush, transforming the area into one of the world’s largest diamond-producing regions. Since then, the association between kimberlites and diamonds has been crucial in the search for new diamond deposits around the globe. [22] [23]
The Marange diamond fields are an area of widespread small-scale diamond production in Chiadzwa, Mutare District, Zimbabwe. 'Although estimates of the reserves contained in this area vary wildly, some have suggested that it could be home to one of the world's richest diamond deposits'. [1]
