Global mined diamond output in 2017 is expected to increase 11.5% year-over-year to 142.3-million carats, worth some $15.6-billion, which itself is a 9.9% increase in forecast total value produced, evaluation by independent diamond analyst Paul Zimnisky has found.
The top ten largest mines in the world by value produced are estimated to represent 58% of global output. De Beers’ Jwaneng mine, in Botswana, is ranked number one, and is estimated to independently produce 15% of the world’s diamonds in value.
