As Featured In
OUR FINAL ARGYLE RESERVE
An historic chapter closes with the release of the last-ever allocation of Argyle-certified pink diamonds. Though the Argyle Mine ceased operations in 2020, a reserve stockpile of pink diamond rough remained. In the years since, Argyle has undertaken the meticulous and time-intensive process of cutting and polishing this final stockpile. This final allocation was released in June 2025, marking the end of all new supply from the world’s only consistent source of natural pink diamonds.
With no remaining production and no equal source globally, Argyle certified pinks have transitioned from rare to truly finite. Their enduring legacy, combined with their extreme scarcity, cements their status as one of the most coveted and resilient alternative assets in the global investment market.
