Argyle Australian Champagne Diamond — 1.18 ct Round | C1 - Light Champagne
Why we chose this stone
This 1.18 carat round brilliant Argyle Australian champagne diamond carries a C1 light champagne colour grade — a soft, luminous warmth, like the first pour of a fine vintage held up to morning light. It's the kind of colour that feels effortless; neither flashy nor understated, but quietly, confidently beautiful.
The round brilliant cut is the world's most loved diamond shape for good reason. With 58 precisely angled facets working in harmony, it captures and returns light with extraordinary brilliance, sending flashes dancing across every surface it touches. In a champagne tone this gentle, that sparkle takes on a honeyed, sun-warmed quality that white diamonds simply cannot replicate.
Mined at the legendary Argyle mine in Western Australia's remote Kimberley region, this diamond carries its own irreplaceable story. The Argyle mine closed permanently in 2020, meaning every stone that bears its name is finite — a piece of Australian natural history that will never 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.
