Which country produces the most diamonds in the world per annum?

<h3>Which country produces the most diamonds in the world per annum?</h3>

I assume it would be an African country like Sierra Leone or Botswana, but perhaps things have changed in recent years so I'm curious to know.

BQ: Which country has gone through a surge in diamond production? By that I mean, who has recently become a big force in diamond mining?

Please provide evidence of your facts or statistics.
And your answer should be accurate to 2012
