The Argyle Diamond Mine is the world’s largest supplier of natural coloured diamonds, from exotic champagne diamonds to the remarkably rare pink diamonds, the signature stone of the Argyle Diamond mine.
The majority of diamonds from the mine are sold as rough or uncut stones by Rio Tinto Diamonds’ central sales and marketing organisation in Antwerp, Belgium.
Rio Tinto Diamonds also operates a niche business cutting and polishing and selling the pink diamond produced by the Argyle Diamond Mine. For further information on selecting an Argyle pink diamond, please visit the Argyle Pink Diamonds website.
Rio Tinto Diamonds sells the majority of the Argyle production as rough, uncut stones direct to the market.
Rio Tinto Diamonds operates a stand-alone pink diamond business to sell and market loose polished pink diamonds from the Argyle mine.
The 4Cs are used in selecting a diamond: colour, clarity, cut and carat.
Diamonds are the most popular and valued gemstones, yet many people know very little about the formation and properties of diamonds.
