Mined diamond production in 2017 is estimated to be 142.3 million carats worth $15.6B (see appendix below), which would be an 11.5% increase in carat volume produced over 2016 and an 9.9% increase in total value produced.
The top 10 largest mines in the world by value produced are estimated to represent 58% of global production. De Beers’ Jwaneng mine in Botswana is ranked number one, and is estimated to independently produce 15% of the world’s diamonds in value.

Russia is estimated to be the largest producing nation by value at 35%, followed by Botswana at 22%, Canada at 14%, Angola at 8%, South Africa at 7%, Namibia at 5%, and Australia at 3%.
Russian diamond production is dominated by ALROSA (RTS: ALRS) which is 58% owned by Russian national and regional governments. The company’s prized Jubilee mine is estimated to produce 9.2M carats worth $1.4B in 2017, which by itself represents 9% of global diamond output by value. Company-wide, ALROSA’s portfolio includes 11 mines and 5 alluvial operations, producing 27% of global diamond production by volume and 33% by value (see Figure 1 for complete company-wide production figures of major producers).
