Argyle Pink Diamonds

The world's most-famous pink diamonds come from the Argyle Diamond Mine in the northern part of the East Kimberley region of Western Australia. Owned by diversified global mining giant Rio Tinto, the mine was opened in 1985. The mine accounts for more than 90% of the world’s pink diamonds. It is believed that the natural pink color was the result of pressure under the earth’s surface slowly bringing the stone closer to the surface and changing its structure. Consequently, it absorbed light and took on a pink color that has not been found anywhere elsewhere in the world.

The price of the pink diamonds depends on their color scale, which ranges from pastel rose to purple red. They are graded on the intensity of color and their value increases with the intensity. The Argyle Diamonds company has its own 9-point grading scale for its gemstones. On its scale, 1 is the deepest color and 9 is the lightest. On average the price of the gems is around 50 times the price of a similar quality white diamond.


Natural red diamonds are the rarest of all natural color stones. So much so that fewer than 10 such diamonds are produced annually in the whole world.
