Deep Passion Oval Black Diamond


Black diamonds are the rarest among all diamonds. They were formed at least 2 billion years ago and are exceptionally rare, found only in Africa and Brazil. They look particularly beautiful set in rose gold, highlighted with champagne diamonds. This passionate beauty is a large stone which needs a bold bespoke design, like a beautiful hand carved mount.

This stone has some inclusions on the underside - this is a natural element of the stone.

These exquisite stones are hand picked by Phoebe to offer you something unusual and special. They can be collected as individual stones in their own right, given as a gift, for example on the birthday every year for a child or loved one, or can be used for a beautiful personal jewellery piece, designed with you by Phoebe.

Or, perhaps you are thinking about proposing and you are worried about picking the perfect ring? This may be your ideal option. Dazzle your loved one with a beautiful stone, and then work together on a design to make your dream ring with Phoebe. Please see our Bespoke page for more information on the design process.

Oval black diamond, 10mm x 8.17mm, 3.99 carats.
