The Argyle Diamond Mine provides 90-95 % of the world’s pink diamonds, offering the vast majority of the worldwide supply of a very rare and valuable commodity. With the mine’s planned closure in 2019, this already rare supply will go scarce.

The demand for Argyle pinks has increased dramatically thanks to the increased economic growth of India and China in addition to the already existing demands of the United States.
​In more than 30 years of mining at the Argyle Mine, no other pink diamond sources have been found anywhere in the world, and none are likely, thanks to the exorbitant costs involved in new mining.
Argyle Pink diamonds are accompanied with either Gemological Institute of America (GIA) Reports and/or Certificates of Authenticity from Rio Tinto, and all Argyle Pinks cut and polished after 2005 are laser inscribed with the Argyle logo (as shown on the GIA Report), or as evidenced by the Certificate of Authenticity.

There are a number of reasons to acquire Argyle pink diamonds:
  • The Rio Tinto Argyle Mine produces 90% to 95% of the world’s pink diamonds;
  • The mine is scheduled for closure between 2018 and 2020;
  • The demand for pink diamonds worldwide has increased dramatically, as a consequence of the wealth created in China and India (the former, being the largest consumer of pink diamonds, next to the United States);
  • The annual supply of pink diamonds is diminishing even more dramatically as the working life of the mine is edging closer to 2018-2020;
  • The Argyle Mine has been in existence since 1985 producing in excess of 30 million carats of diamonds per annum, of which less than 0.001% are pink diamonds, and only a portion of these are cut and polished and considered investment grade. To put this in perspective, a year’s supply of cut and polished Argyle pink diamonds would fit in the palm of your hand;
  • There have been no new discoveries of diamond mines producing pink diamonds since the formation of the Argyle Mine almost 30 years ago, and none are anticipated due to the high cost of bringing a mine into production (in excess of one billion dollars), and the regulatory and environ-mental hurdles which are inherent in creating one;
  • A one (1) carat pink diamond available for sale in 1980 for $10,000 now sells for between $250,000 to $400,000 depending on the color saturation and quality of the stone;
  • Argyle pink diamonds have a unique aesthetic beauty based upon their saturation of color which differentiates an Argyle pink from the limited quantities of pink diamonds which emanate from South Africa and South America;
  • Argyle pink diamonds are accompanied with either Gemological Institute of America (GIA) Reports and/or Certificates of Authenticity from Rio Tinto, and all Argyle pinks cut and polished after 2005 are laser inscribed with the Argyle logo (as shown on the GIA Report), or as evidenced by the Certificate of Authenticity.
