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

Why we chose this stone

At C2, colour reads as a gentle gold rather than a bold statement, and this 0.70ct round brilliant wears that restraint well. The brilliant cut's dense facet pattern was built to maximise brightness and fire, and with a colour this light, sparkle stays the star of the show while the soft champagne tone plays quietly underneath, adding character without demanding attention. It's a grade well suited to buyers after something distinctive but easy to wear — genuine Argyle rarity that doesn't require the design to be built around it. It comes from the East Kimberley region of Western Australia, where the mine operated until its closure ended production of these diamonds permanently.

At 0.70ct, this is a practical, versatile size for a centre stone — substantial enough to anchor a classic solitaire, restrained enough in colour to sit comfortably with white metal or diamond accents. It's a genuinely rare stone regardless of its subtle tone, from a source that will never be replenished.
