Diarough buys its rough supply from a variety of sources, including the DTC, Alrosa and Rio Tinto Diamonds, the world’s three largest diamond miners. After assorting the various rough, Diarough sells a portion of it on the open market, while processing the rest for manufacturing through its own pipeline. Through its expertise in manufacturing, Diarough is able to transform this rough into the sparkling diamonds craved across the world.
