Ask a question

This very pretty ring from 1930 features an unheated vibrant sapphire surrounded by a pierced platinum plaque with early modern cut brilliant diamonds.

It is engraved for July 12th 1930 – exactly 90 years ago today! (I had no idea before I decided to list it, then closely read the inscription.)

The millegrain settings surrounding the stones add delicacy, and the small shoulder diamonds are a lovely finishing touch.
