Argyle Australian Champagne Diamond — 0.70ct Radiant Cut| C7 - Dark Champagne
Why we chose this stone
Where C4 leans deep and burnished, C7 sits lighter — a pale, honeyed gold that reads almost like sunlight caught mid-afternoon. This 0.70 carat stone carries that softer end of the champagne spectrum, understated rather than bold, the kind of colour that reveals itself slowly rather than announcing it. The radiant cut suits it well: its clean, faceted structure gives the stone a lively, faceted sparkle that keeps a paler champagne diamond from ever looking washed out.
It carries the same origin as every stone in this collection — the Argyle mine in Western Australia, closed now, its output finished for good. There will be no more of these. At 0.70 carats, this is a stone built for versatility: a quiet accent, a considered gift, an entry point into a category of diamond that's becoming harder to find with each passing year. Small in size, but part of something that no longer exists to be replaced.

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.
