|Around 135 million carats of rough diamonds, valued at $17.8 billion, will be mined in 2014, which would represent an increase of approximately 3% over 2013. 50 mines are estimated to account for 90% of global rough diamond supply in 2014, with the balance coming from private or small-scale operations.|
The Marange diamond fields, a 300 square-mile alluvial deposit in Zimbabwe, was ranked the worlds largest source of diamonds in 2013 in terms of total carats produced, estimated to have produced almost 17 million carats or 13% of global supply. It appears that 2013 production levels will not be sustained in 2014. Marange production is estimated to drop to 8-12 million carats or less.
In 2013, Botswana’s Orapa mine was the worlds largest diamond mine in terms of total value of carats produced. In 2014 Orapa is again estimated to be the worlds largest by value estimated to produce $1.9 billion worth of diamonds. In 2014, the Orapa mine is also estimated to be the worlds largest in terms of carats produced with 12.9 million carats.
