Argyle Australian Champagne Diamond — 0.25 ct Oval | C3 - Med Champagne
Why we chose this stone
A quarter of a carat is a milestone size for many buyers, and this 0.25 ct oval-cut Australian champagne diamond makes the most of it. The oval shape gives a long, flattering line and a generous face-up presence, so it sits comfortably as the centre of a ring or the focal point of a pendant. This natural stone was mined in the Kimberley region of Western Australia, home to the Argyle mine, which closed in 2020 after decades of producing some of the most distinctive coloured diamonds in the world. Because that source can never be reopened, each stone from it is a finite piece of Australian history. It is ethically sourced and comes with a mine certificate of authenticity documenting its provenance. Hope Diamonds offers it as a loose stone, so you can choose the metal, the setting, and the story you want to build around it.

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.
