Rio Tinto is one of the largest producers of rough diamonds in the world, unearthing stones of many different colours, shapes and sizes. Our diverse production of white and coloured diamonds caters to all diamond jewellery segments in key markets around the world.

Our Diavik mine, for example, produces a high proportion of large, white, gem-quality diamonds, traditionally associated with engagement rings, luxury jewellery and collector pieces. Our Argyle mine, by contrast, produces predominantly small, coloured stones of diverse quality – generally destined for the more affordable fashion jewellery market – as well as the rare and highly prized pink diamonds sought after by high-end collectors, designers and diamond connoisseurs. Argyle is the world’s leading provider of natural coloured diamonds, steadily supplying the world market with gems in champagne, cognac and grey (Silvermist) tones, as well as many shades of pink. The coloured diamonds have found an enthusiastic market in the United States, Japan and Australia, and are now finding strong new markets in China and India.

All of our rough diamonds are sorted and prepared for sale at our sales and marketing headquarters in Antwerp, Belgium, except the pink diamonds which are retained for cutting and polishing by specialist artisans at Argyle’s headquarters in Perth, Western Australia. Argyle Pink Diamonds are sold to an exclusive group of international partners and ateliers.
