Argyle pink diamonds, produced at Rio Tinto's Argyle Diamond Mine in Western Australia, are coveted as the world's most sought-after diamonds. The Argyle Diamond Mine produces more than 90 per cent of the world's pink diamond supply, which are sold in a range of colors and sizes to an international customer base, and only now are making their way to collectors in the United States.
The market for pink diamonds is quite separate from white diamonds, and due to their rarity, pink diamonds typically command prices far in excess of their colorless counterparts. The finest and rarest diamonds are reserved for the annual Argyle Pink Diamonds Signature Tender. Consumers and collectors appreciate Argyle pink diamonds unmounted or in jewelry collections available exclusively at participating U.S. Select Ateliers.
