Argyle Australian Champagne Diamond — 0.31 ct Emerald | C4 - Med Champagne
Why we chose this stone
The emerald cut has its roots in the Art Deco era, and this 0.31 ct stone carries that heritage well. It’s a natural Australian champagne diamond from the Argyle mine region in Western Australia’s Kimberley, cut with long, stepped facets that give it a clean, architectural look. Argyle closed in 2020, so every diamond from this source is now part of a finite supply, and that gives this stone a story that’s hard to find elsewhere. It’s sold loose and includes a mine certificate of authenticity, so its origin is documented from the start. Whether you’re planning a bespoke design or adding to a collection, it’s ready to be set, and we ship insured from our Perth studio across Australia.

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.
