Pink diamonds are one of the rarest and most valuable natural commodities on earth. The recently decommissioned Argyle diamond mine in Australia was known as the largest source of high-quality pink diamonds in the world. Now only a small number of diamond mines continue to mine for these precious stones.

The pink diamonds from the Argyle mine are so unique that experienced diamantaires can often identify the origin of the diamond by looking closely into the stone. The pink colouring of an Australian pink diamond is so vibrant that regardless of the size, they are considered as an excellent investment.
