Art Deco French 0.50 Carat Diamond and Blue Sapphire Ring in Platinum

£2,995.00 £1,797.00

This ring is extraordinary. It’s so big it needs its own postcode. And that postcode would be W1K. It’s immense and beautiful! It’s got a modernist, almost robotic futuristic vibe to it. It’s strong and architectural and a gorgeous example of Art Deco. The beautiful central Diamond is estimated to weigh around 0.50 carats and it’s glorious alongside the French cut Blue Sapphires, which are seamlessly set into Platinum.

This is a French ring. It’s got no hallmarks or makers marks that we can see, but it can only really be French and it tests for Platinum.  With a bit of research you may be able to attribute it to a jewellery house. It’s magnificent quality, and utterly joyful and almost certainly made by someone of note. 

It will fit a size M 1/2 (US 6 1/4) and could be sized to fit. If you need an alternate size, please write it in the Notes section upon checkout and we are happy to size it accordingly, free of charge. Please note, re-sizing can add up to two weeks to delivery times and your purchase will still be returnable for a full refund, as per our Refund Policy.

All of our rings come in a beautiful velvet box, as seen in our pictures. Please note the colour you would prefer in the Notes section, or, leave it blank and we’re happy to surprise you with the colour we think will best suit your beautiful new item!
