The mine is a source of white, champagne, and pink diamonds as well as other rare colours such as red and blue, but its name is most commonly associated with it’s signature stone, the Argyle Certified Pink.

Over the past 11 years (2005 – 2016) pink diamonds have appreciated in value by around 365%, with the rare Type 1a Argyle Certified Pink Diamond exhibiting the most significant gains.

They have outperformed all other reliable economic indicators including the Australian All Ordinaries Index and the Australian Property Market by a considerable margin.

The Argyle Certified mine may be the largest source of pink diamonds that the world will ever see, but there are only so many diamonds left within it, which has seen them gaining in popularity among investors, diamond enthusiasts, and celebrities.
