Art Deco sapphire and diamond ring in white gold and platinum, Birmingham 1925


Ask a question

Here’s an Art Deco ring made from diamonds and a contrasting precious gem – natural sapphire, in this example.

The 1925 hallmark is interesting because not many hallmarked rings were made during this time. Possibly this was because bands were very narrow, so there was simply a lack of space. And platinum hallmarking appears to be all but non-existent beyond a simple stamp.

With so many reproductions around it’s reassuring to see this guarantee of age.

The platinum top provides a superfine finish. The sapphires have not been heat treated.

This is a jewel that could be worn carefully every day, unlike some of my more delicate rings.
