Ask a question

The 1920s were a crossroad in jewellery design. Strong geometric designs were combined with the exquisite craft of the preceding centuries.

Platinum was the conduit, allowing strength and delicacy to coexist in the same piece.

The details – including the fine understructure and the millegraining –place this ring firmly in its time.

And black and white were the colours of the day. So daring, so strong – so not Edwardian.
