Diamond Industry Around the world, 8 out of 10 diamonds on the market were cut and polished in Surat. This industry earns India about 10 billion USD in annual exports. A legacy of old Dutch trade links, it began after a Surti entrepreneur returned from East Africa bringing diamond cutters. The rough diamonds themselves, however, come to Surat as rough crystals ripped out mainly from deep under the earth of South Africa and other regions of the continent, and go from here as smooth gems to Antwerp, Belgium where the international diamond trade is run mainly by Hasidic Jews and Jains from Palanpur in North Gujarat.
Inquire at the Tourist Office to arrange a visit to some of the diamond-cutting workshops tucked away in the city.
