Argyle Australian Champagne Diamond — 0.93ct Round Brilliant Cut| C3 - Light Champagne

Why we chose this stone

Nearly a full carat and graded C1, this round brilliant sits at an appealing intersection: substantial size paired with the lightest, most restrained colour on the Argyle champagne scale. The warmth here is barely a suggestion — enough to distinguish the stone from a standard white diamond under close inspection, not enough to change the overall impression of brightness. On a brilliant cut this size, that's a real advantage; the facet pattern is doing what it does best, throwing light generously, with only the faintest golden cast running through it. It comes from the East Kimberley region of Western Australia, mined before the Argyle pipe closed and ended production of these diamonds entirely.

Buyers drawn to large, pale champagne stones like this one are often after a diamond that reads as classic and versatile first, rare and storied second — something that will sit comfortably in a traditional solitaire or halo without needing the setting built around its colour. At 0.92ct, it's a genuine statement size, with a C1 grade that keeps it easy to wear.
