Our base supply scenario calls for moderate growth in the supply of rough diamonds. It assumes that new mines now under development will add 20 million carats to the supply and takes into account a slight depletion of existing diamond resources and absence of significant new discoveries of diamond deposits in recent years. The resulting forecast calls for rough-diamond production to reach 163 million carats in 2019, below the precrisis production of 177 million carats in 2005, which dropped to 163 carats by 2008
