Argyle Australian Champagne Diamond — 0.72ct Round Brilliant Cut| C8 - Dark Champagne

Why we chose this stone

At C8, colour stops being a subtle accent and becomes the whole point — this is the darkest grade the Argyle scale goes, a rich, saturated cognac that reads closer to chocolate or dark amber than anything you'd call "champagne." This 0.72ct round brilliant carries that intensity confidently even at a more modest carat weight, proof that a strong C8 doesn't need a large stone to make an impression. The brilliant's facet pattern keeps that dark tone from ever looking flat, breaking it into shifting pools of colour and warmer glints as the stone moves. It comes from the East Kimberley region of Western Australia, where the Argyle mine produced these diamonds until its closure brought that supply to a permanent end.

C8 stones were always the rarest of the champagne-to-cognac range, since the darkest colours occurred least often in the rough Argyle pulled from the ground. At 0.72ct, this one offers genuine top-grade colour at a size that suits a ring, pendant, or pair of earrings without the scale — or the price — of a full carat stone. For anyone chasing the deepest colour the Argyle mine ever produced, this is about as dark as it gets
