24/7 Wall St. has uncovered the 10 richest diamond mines in the world.
Even though the international diamond mining community remains
tight-lipped on its operations, we do know who the world’s largest
diamond miners are (De Beers, Alrosa, Rio Tinto, and BHP Billiton) as
well as the five most productive diamond mining countries (Russia,
Botswana, Democratic Republic of Congo, South Africa and Canada).

These five countries alone make up more than three-quarters of the
world’s diamond production by weight. Clearly, only a select few hold
the reins of a massive diamond production.

Here are the ten most profitable diamond mines in the world for 2010
according to the carat quantity each mine was able to produce.

10 Kimberley

original mine closed in 1914 and the underground mine closed in 1995.
• De Beers, the original owner, sold underground mining rights to Petra in
2007, and Petra produced about 100,000 carats from the mine in 2010.
• De Beers is re-treating the dumps on the surface and recovered 823,000
carats in 2010 from nearly 5.5 million tons of rock.

35% of which are gem quality. Production in 2009 totaled 7.5 million carats.
