Pink diamonds are legendary.
They’ve been found historically in India, Africa, and Brazil. Fabulous old cut pink diamonds have graced the crown jewels of India and France among others.
Instead of the usual kimberlite pipe where most of the world’s diamonds are found, the pink diamonds at Argyle are sourced from a volcanic lamproite pipe.
Most of the world’s current production of pink diamonds comes from the Argyle mine.
There are only an estimated 500 tender-quality pink diamonds left to be discovered in the Argyle mine before it shuts down. There is no other consistent source for pink diamonds.
