AUTHENTICALLY ARGYLE

The rarest diamonds on earth. Now rarer still.

The Argyle mine closed in 2020 — permanently. Every pink, blue, red and champagne diamond from the world's most celebrated source has already been unearthed. What remains is all there will ever be.

Whether you are acquiring a stone to keep, to craft into something worn and passed down, or to hold as a rare piece of natural history — we are here to guide you with honesty and expertise.
