Argyle Australian Champagne Diamond — 0.50ct Radiant Cut| C4 - Medium Champagne
Why we chose this stone
Half a carat, radiant cut, C4 grade — the specs match another piece in this collection, but no two champagne diamonds wear their colour quite the same way. This stone leans into that warm, gold-toned register of the spectrum, with the radiant cut's angular facets drawing out brightness alongside depth, so the colour never sits flat.
Its provenance is shared with every stone here — the Argyle mine in Western Australia, closed for good, its stones no longer being drawn from the earth. There will be no more of these. At 0.50 carats, it's a size built for versatility, whether as a standalone piece or one stone within a wider collection — proof that even at this scale, provenance and colour together create something genuinely singular.

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.
