Most people have never heard of the Argyle mine, and yet its closure has permanently reshaped the entire pink diamond market. Here is why one remote mine in Western Australia mattered so much.
One mine, almost the entire world's supply
For 37 years, the Argyle mine in the Kimberley region of Western Australia produced around 90 per cent of the world's pink diamonds, as well as the vast majority of its red diamonds. No other source on earth has ever come close to matching that output. Over its lifetime, the mine produced more than 865 million carats of rough diamonds in total.
Pink diamonds were always the rarity within the rarity
Even at Argyle, pink stones were never common. They made up less than one per cent of everything the mine produced, meaning the mine mined hundreds of millions of carats just to yield a relative handful of genuine pinks each year.
Then, in 2020, it simply stopped
Argyle ceased operations in November 2020, after its supply was finally exhausted. With it, roughly 90 per cent of the world's pink diamond supply vanished from production entirely, and no other mine has demonstrated anything close to that capacity since.
Why this matters so much for value
Since the closure, prices for genuine Argyle pink diamonds have climbed sharply. Some reports show fancy vivid pink diamonds appreciating over 400 per cent since 2005, with that growth accelerating further once the mine shut for good. This is not a typical supply dip that might recover in a few years; it is a permanent reduction, since no replacement source has emerged.
What it means if you are buying today
A pink diamond bought now is, in a very real sense, finite in a way few other purchases are. With no new Argyle stones ever entering the market again, each verified piece represents a slice of a supply that can only shrink from here, not grow.
