Argyle is the world’s primary source of the highly prized rare pink diamond which has become Argyle’s signature stone. Sought-after by collectors, investors and connoisseurs the world-over, the finest pink stones are retained by the company in Perth, where they are cut and polished in Argyle's own facility and sold by international tender. These exquisite signature stones vary in colour from pale pink to intense purple reds and command prices up to twenty times that of a white diamond.
