Rio Tinto is one of the world’s leading diamond producers with world class mines in Australia (the now closed Argyle Diamond Mine) and Canada (the Diavik Diamond Mine). We distribute rough diamonds through our carefully selected partners—the Rio Tinto Select Diamantaires. We rely on these companies to maintain the authentic Chain of Custody of our diamonds, all the way through the pipeline.

Rio Tinto is a leading supporter of the Kimberley Process, a founding member of both the Responsible Jewelry Council and the Diamond Producers Association, a partner and advocate of the Diamond Empowerment Fund and has been an important and active participant in the international diamond market for over three decades.
