Pink diamonds are among the rarest of natural gemstones, with expectations of less than a decade of stones available to be mined. Originating in the east Kimberley region of Western Australia, the Argyle mines are responsible for 90% of the world’s pink diamond supply.
Pink diamonds are among the rarest of the world’s diamonds, with only 0.1% of the worlds 20 million carat diamond output classified as pink. Because of this, pink diamonds are referred to by many as one of life’s true treasures, for their undeniable beauty, and the exclusivity that comes alongside their ownership.
The exact source of pink diamonds’ mesmerising colour is still largely unknown and argued, however it is often thought that as the diamonds arise to the earth’s surface, the pressure alters the diamond’s structure, allowing it to absorb light and produce the remarkable shades of pink.
Given their rarity, pink diamonds are typically valued at 20 times the value of a traditional white diamond of similar quality. As the world’s primary supplier of pink diamonds, the closure of the Argyle mine in November 2020 is expected to further increase the rarity and value of such stones as supply continues to become even more limited.
Not only are Argyle pink diamonds completely natural in their colour and clarity, but as leaders in the industry Argyle have also created their own, dedicated colour grading system ranging from red to pink, purplish pink, pink rose, pink champagne and finally to violet.
