Argyle Color
The Argyle mine is one of the largest mines in the world, and is the main source of the rare natural fancy pink diamonds. It produces about 90 percent of the world’s supply of pink diamonds. The stones are so highly valued that between 40 and 60 of the best diamonds are put out to tender every year. The natural red diamond, one of the rarest among fancy color diamonds, is so rare that only a few stones are mined each year. Even these diamonds, produced by the Argyle mine are not pure red but rather graded as fancy-brownish-red, vivid-purplish-pink, Fancy purplish-red, and a few other variety of hues.
