Argyle Australian Champagne Diamond — 0.86 ct Round | C6 - Dark Champagne
Why we chose this stone
This 0.86ct Argyle diamond glows with a deep, saturated cognac warmth — rich, dimensional, and unmistakably beautiful. The round brilliant cut, with its 57 or 58 precisely angled facets, is the most optically efficient shape ever devised, and in a stone of this colour intensity, it creates a display of warm fire that is genuinely arresting.
SI1 clarity means inclusions are present but not visible without magnification. The colour saturation of a C6 stone more than compensates — in fact, at this depth of colour, the eye is entirely drawn to the warmth and brilliance rather than looking for clarity characteristics.
An Argyle C6 round brilliant of this quality is a collector's stone. Rich in colour, exceptional in cut, and carrying the provenance of a mine that will never reopen.

I’ve purchased several diamonds and a range of other stones including opals, sapphires and more from Julie. The quality and price point was excellent. Her calm, relaxed approach to creating bespoke jewellery has been spot on every time. I wouldn’t go anywhere else.

The experience I had throughout this process was amazing. Not knowing much about this area, Julie took the time to explain everything to me in detail, which gave me a lot of comfort.I could not fault the price, the quality and experience I had with Hope Diamonds. A very very successful journey with Julie and the team :) I highly recommend Hope Diamonds.
