What do diamond companies do?
Diamond companies mine rough stones and sell them to cutters, who polish them in specialist workshops and trade them through dealers and diamond bourses to jewellers. A few mining groups produce most rough diamonds, while cutting, grading and trading are done by many family firms in a handful of trading centres, and laboratory-grown stones now compete with mined ones.
Our data comes from the business registers of 39 countries. SIC has no code of its own for diamond companies: they sit in SIC major group 50 (wholesale trade-durable goods) and major group 39 (miscellaneous manufacturing industries), so within that we select them on the CompanyData industry label for diamond traders and cutters. In NACE, the European code those registers use, 4,114 of them (90%) sit in classes 32.12 (manufacture of jewellery and related articles) and 46.48 (wholesale of watches and jewellery), part of divisions 32 (other manufacturing) and 46 (wholesale trade, except of motor vehicles and motorcycles).
