Argyle Australian Champagne Diamond — 0.60ct Round Brilliant Cut| C1 - Light Champagne

Why we chose this stone

The round brilliant is the cut built for maximum fire and sparkle, and paired with a C1 grade — the lightest on the champagne scale — that's exactly what comes through here. At 0.60ct, there's enough size for the brilliant's 57 or 58 facets to do their job properly, throwing light in every direction with only the faintest golden warmth colouring it. It's a diamond that, at a glance, could easily pass for a warmer white stone, and for many buyers that's precisely the draw: the rarity and provenance of an Argyle diamond, without a strong colour statement to work around. It comes from the East Kimberley region of Western Australia, the source of every Argyle diamond mined before the pipe's closure ended production for good.

A C1 round brilliant like this one tends to appeal to people who want their coloured diamond to read as classic rather than distinctly "champagne" — a diamond that slots into a traditional solitaire or halo setting without demanding the ring be redesigned around it. At 0.60ct, it's also a genuinely useful size: substantial enough for a centre stone, subtle enough in colour to stay versatile.
