After 40 years of operations, the Argyle Diamond Mine in East Kimberley, Australia is finally set to close by the end of 2020.
The mine is responsible for over 90% of the worldwide output of pink diamonds, the most coveted and rarest type of coloured diamonds, and its closure will thus dramatically reduce global supply of this already scarce product.
In addition, due to their ever-increasing allure and new status as collector’s items, there is no doubt that demand will rise as a response to the imminent zero-supply. This is illustrated by the recent auction prices paid for pink diamonds, such as the $ 7.5 million paid for the 3.43ct fancy vivid purplish pink “Bubble Gum Pink” diamond at a Christie’s auction.
