Rio Tinto is one of the world's leading producers of rough diamonds with three diamond mines and a fourth advanced diamond project.
In Australia Rio Tinto owns the Argyle Diamond Mine, located in the rugged East Kimberley region of Western Australia. Operating since 1983, the Argyle Diamond Mine is the world's largest producer of coloured diamonds, including champagnes, cognacs, greys, and the rarest of all, pink diamonds.
Rio Tinto sells its Argyle production as predominantly rough diamonds, except for the rare Argyle pink diamonds, which are cut and polished in Perth, Western Australia.
