The cut and polished diamonds are exported to United States of America, Japan, Belgium, Hong Kong, Switzerland and Thailand. Of these, USA, Japan and Switzerland are consumer markets and the rest of them are trading countries. It is mostly the same commission agents who supply roughs to the firms on behalf of the sight-holders, who also take the finished product for export. It is the commission agents who bargain on the commercial terms with the units. There are about 2,000 exporting concerns in India, which are registered with the Gem and Jewelry Export Promotion Council (GJEPC), Mumbai. About 95% of the exports are routed through Mumbai based exporters.
The other development has been the move by some companies to manufacture large size and fancy cut diamonds. A country that entered the international diamond industry as a manufacturer of small diamonds only, today, is producing virtually stones of every shape, size and colour. Most companies are now innovating and developing new cuts, some of them being patented internationally.
