De Beers estimates that overall global rough diamond production increased by three per cent from 2012 to US$18 billion in 2013. Measured in carats, the increase was seven per cent, to reach 146 million carats. This is still below the production peak in 2005, when overall production was above 176 million carats.

The largest diamond producing country, by volume, is Russia, which in 2013 produced 25 per cent of total carats, and 26 per cent of overall rough diamond value. Botswana produced 16 per cent of carats, corresponding to 21 per cent of overall value.
