Argyle Australian Champagne Diamond — 0.70ct Round Brilliant Cut| C2 - Light Champagne

Why we chose this stone

Some champagne diamonds are chosen for their colour first. This one is chosen for its sparkle. At C2, the tone is barely more than a suggestion — a faint golden warmth sitting just beneath a wash of white light — which means the round brilliant's facet pattern gets to do exactly what it does best: throw fire and scintillation in every direction, unobstructed by heavier colour. At 0.70ct, there's real size behind that sparkle, enough to make a genuine impression as a centre stone while still reading, at a glance, close to a traditional white diamond. It comes from the East Kimberley region of Western Australia, mined before the Argyle pipe's closure brought that supply to a permanent end.

This is a stone for someone who wants the story of an Argyle diamond — the rarity, the closed mine, the provenance — without the colour becoming the headline. It slots easily into a classic solitaire or halo, pairs cleanly with white diamonds or white metal, and carries its rarity quietly rather than loudly.
