Our diamonds have a unique story
Rio Tinto is one of the world’s major diamond producers, owning 100% of both the Diavik Diamond Mine in Canada and the now closed Argyle Diamond Mine in Australia.
Rio Tinto’s Select Diamantaires are your gateway to some of the most extraordinary and responsibly-sourced diamonds in the world. These companies represent the best of the diamond industry and play a critical role in guaranteeing that the audited Rio Tinto Diamonds Chain of Custody platform remains intact.
Each Select Diamantaire has been carefully selected for their expertise in diamond trading, cutting and polishing, and marketing—qualifying them to receive a regular and consistent supply of diamonds from Rio Tinto’s mines. Their stewardship and commitment ensure your access to authentic, responsibly-mined diamonds.
We invite you to explore our roster of Select Diamantaires and their extensive capabilities to find one that meets your needs.Directory
