Art Deco Platinum, Sapphire & Diamond Square Ring

Rare Find
125 Admirers

A stunning platinum ring that was made in the 1920s. It has been set with a three quarters of a carat bright white transition cut diamond with four small diamonds within a square setting. Around it are square cut sapphires with triangular shaped sapphires set in to the canted corners. There is millgrain detail to the edges that adds to the overall design of the ring. It is a beautiful ring and would be an ideal engagement ring.
