As part of its commitment to transparency, the Kimberly Process recently released world diamond production by value for 2006:
World Production by value (2006)
Russian Federation 21%
South Africa 11%
The chart below shows that Botswana and the Russian Federation produce about 50% of diamonds by value.
World Production by Volume (2006)
Russian Federation 22%
Democratic Republic of Congo 17%
South Africa 9%
Total: 175,538,127 carats
As you can see, Russia and Botswana also are dominant on the “volume” side, although the positions of the top two are switched. In addition, Australia and the Democratic Republic of Congo, which don’t produce a lot by value (meaning they produce small stones) do produce a lot by volume. It should be noted that this is only the stones that go through the Kimberly Process. But the amount of goods that are falling through the cracks is very minute, since 99% of all goods are traded through Kimberly.
