Antique Old Mine Brilliant Cut Diamond 1.66 ct | I VS2
Why we chose this stone
There's a particular kind of sparkle that only comes from a diamond cut by hand, without the mathematical precision of modern faceting machines — and this 1.66 carat Old Mine Brilliant is a beautiful example of it. Cushion-shaped with a high crown and open culet, this cut style dominated diamond jewellery through the 19th and early 20th centuries, prized for its soft, flickering light rather than the sharp, uniform brilliance of today's round cuts.
Guaranteed at least 80 years old, this stone was rescued from an antique setting and sourced through Antwerp, a city whose diamond trade history stretches back centuries. Its I colour grade places it within the near-colourless range, and VS2 clarity gives it excellent transparency for a stone of this age and cutting style — a combination that's genuinely difficult to find in the antique diamond market.
At 1.66 carats, this is a versatile size for anyone wanting to start or add to an antique diamond collection without compromising on quality or authenticity.

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.
