Australian Pink Diamonds
Rio Tinto’s Argyle diamond mine is located in the remote East Kimberley region of Western Australia. This mine was established in 1983, and is the world’s largest supplier of natural coloured diamonds.
When it comes to pink diamonds, Rio Tinto’s Argyle mine is the world’s only reliable source. Despite this, less than 0.1% of the diamonds extracted from the mine are pink. These diamonds are so rare that just 50-60 diamonds are sold per year. And this is the world’s largest supplier, making up 90% of the global supply! Rio Tinto have set the closure of the mine for 2020 due to lack of supply, so Australian pink diamonds provide a smart investment opportunity.
Pink Diamond Colouring
Rio Tinto have their own approach to pink diamond colour grading. Their pink diamonds are divided into four colour categories: PP (Purplish Pink), P (Pink), Pink Rose (PR) and PC (Pink Champagne). Rio Tinto also recognise two Red hues – Red and Purplish Red – as well as Blue Violet colouring. The diamonds are also graded in colour intensity, and are given a number between 1 (the highest) and 9 (the lowest).
