Argyle Australian Champagne Diamond — 0.70 ct Round | C3 Med Champagne
Why we chose this stone
Warm, balanced, and effortlessly wearable. This 0.70 carat round brilliant champagne diamond is a C3 — a medium tone that sits right in the sweet spot of the champagne colour spectrum, warm enough to feel distinctive, soft enough to suit almost any design. It's a natural Australian diamond prized for its rarity and its ability to bring understated colour to a classic shape.
The round brilliant cut is the most timeless of all diamond shapes, and its precise faceting is built to maximise light return. Here, that means the champagne hue shimmers evenly across the stone with every movement, giving it a soft golden glow rather than a single flat tone.
Sourced from the Kimberley region of Western Australia, this diamond carries the provenance of one of the world's most celebrated diamond-producing regions. It comes with a mine certificate of authenticity, confirming its natural Australian origin. Sold loose and unset — ready to be placed into the setting of your choice.

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.
