A reliable supply of rough diamonds has always been a core strength of the Blue Star Group. Besides access to direct sources of rough as a sightholder of the DTC, Blue Star also purchases from a range of other primary source suppliers. This assured source of quality rough translates into consistent, tailored supplies for its customers. Blue Star can in this regard also rely on the wide variety of 'quality' rough assortments, offered by Arjav Diamonds NV a long standing business relationship and one of the major rough distributors on the Antwerp market.
