Rio Tinto operates a fully integrated global diamond exploration, mining and sales and marketing business, with a strong and trusted profile in both established and developing markets. Rio Tinto's diamonds business comprises some 2,000 people around the world.
As one of the world's largest producers of rough diamonds, we are committed to providing a reliable supply of white and coloured diamonds that are mined to the highest possible health, safety and environmental standards.
Our business model is based on strategic partnerships and we work with all aspects of the supply chain, from mine to market, to develop markets for our products. Like other Rio Tinto companies, we are strongly committed to improving the long-term future for the diverse communities in which our mines operate.
Currently, we have a controlling interest in two underground mines: the Argyle mine in Western Australia, operating since 1983; the Diavik mine in Canada’s Northwest Territories, operating since 2003. Rio Tinto has 100% ownership of the Argyle mine and a 60% interest in the Diavik mine. We operate two world class underground mines in very different geographies and conditions, from the icy, subarctic tundra in Canada to the contrastingly hot, savannah type conditions in north Western Australia. While united by Rio Tinto’s operating standards and values, this means that each of our mines has their own distinct character and footprint, and their own distinct operating challenges.
Rio Tinto owns and operates the Argyle Diamond Mine in the remote East Kimberley region of Western Australia. The mine has been operating since 1983 and has produced more than 800 million carats of rough diamonds. It is the world's largest supplier of natural coloured diamonds and the world’s only supplier of rare pink diamonds.
Rio Tinto owns a 60 per cent interest in, and operates, the Diavik Diamond Mine in Canada's remote Northwest Territories, 220km south of the Arctic Circle. The design, construction and operation of the Diavik mine is an epic saga of success on a grand scale in the most forbidding of places. Diavik commenced production in 2003 and has an annual production of some 6-7 million carats of predominantly large, white gem-quality diamonds.
From 2004 to 2015 Rio Tinto operated the Murowa Diamond Mine, located near Zvishavane in south central Zimbabwe where it produced around 400,000 carats per annum of large, predominately white, gem-quality diamonds. In June 2015, Rio Tinto sold its 78 per cent interest in Murowa Diamonds to RZ Murowa Holdings Limited, an independent Zimbabwean mining company listed on the Zimbabwean Stock Exchange.
