The sales and marketing arm of the De Beers Group, Diamond Trading Company (DTC), only sells rough diamonds to a select group of companies, called Sightholders. Historically, these names have been kept somewhat confidential but the DTC recent created a sightholder directory that is open to the public.
The directory can be accessed online at www.dtc.com/sightholder and provides information on the 93 DTC sightholders and over 500 Sightholder associated companies.
Sightholder information includes descriptions of the companies and their involvement in consumer-focused marketing initiatives. The directory contains a wealth of information about these companies that power the worldwide diamond industry.
