About Pink Diamonds

Pink diamonds are beautiful, valuable and exceptionally rare. Our range of Pink Diamonds are sourced from the world’s leading producer – Rio Tinto’s Argyle Diamond Mine in the East Kimberley region of Western Australia. This mine has been responsible for 90% of the world’s pink diamond supply, yet the gems are so rare that this only equates to 50 or 60 pink diamonds each year. 

Pink diamonds are coveted for their beauty and rarity, but this is even more true for diamonds from Rio Tinto’s Argyle Diamond Mine. Australian pink diamonds have a distinctly radiant depth of pink colour that is rarely found in pink diamonds from other countries, which tend to be softer and more pale.

The Origin of Australian Pink Diamonds

In 1979, a group of geologists were digging in the heart of a region known as East Kimberley, in Western Australia. They spotted something glimmering in an anthill, and it turned out to be a depository of diamonds. Of all the stones that Rio Tinto’s Argyle Diamond Mine would reveal, the most highly prized and supremely precious are their rare pink diamonds. Only a very small percentage of the Diamonds mined by the mine are pink – less than 0.1% in fact. Australian Argyle Pink Diamonds are beyond rare – they have become an Australian ‘heritage’ item that is highly sought after by collectors and investors from all around the globe.

Collectible Pink Diamond Investment

Rio Tinto’s Argyle Diamond Mine closed November 2020, due to exhausted supply. With a global decrease in pink diamond availability, this has resulted in an already-rare Australian pink diamond being even more sought after!

Pink diamonds have experienced the highest interest growth of all coloured diamonds, with an average investment growth of 15% (it has reached up to 20%). Over the last 20 years, the prices of pink diamonds have never dropped – and experts don’t believe they ever will. All of our Australian pink diamonds are supported by an Argyle Lot Number and/or Certificate, which guarantees their quality and authenticity.
