Antique Old Mine Cushion Diamond 0.64 ct | K SI1
Why we chose this stone
Every old mine cut diamond is one of a kind — not by marketing claim, but by simple fact. No two were ever cut quite the same way, because no two hands cut them.
This 0.64ct old mine cushion cut diamond was hand-cut more than 80 years ago and rescued from estate jewellery sourced in Antwerp. Cut using techniques and tools that predate modern precision faceting, it carries the hallmarks of the old mine style: a high crown, a small table, and larger, open facets that produce a soft, warm brilliance quite different from the sharper sparkle of a contemporary round brilliant. Its cushion shape, with softly rounded corners, gives it an unmistakably antique presence.
This is a stone that has already outlived the era it was made in, and the people who made it — and it's ready for a new setting, a new owner, and a new story.

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.
