A rough diamond is a diamond in its natural state that has not yet been cut. "Cutting" is the multi-step process performed on mined rough diamonds to convert them into gems.
The average value per carat for Australian diamonds is relatively low by world standards. Antwerp in Belgium is the world's primary diamond trading and distribution centre. India is the world's largest centre for the manufacturing (cutting and polishing) of diamonds.
Australia is one of 54 participants representing 81 countries in the Kimberley Process Certification Scheme (KPCS). The KPCS is a joint government, industry and civil society initiative to stem the flow of rough diamonds used by rebel movements by banning the trade of rough diamonds with non-participants.
