Avant Garde 1.10 Carat Sapphire & Transitional Cut Diamond Ring, French, circa 1955

Item #: 4464S203.

A superbly unusual ring. The royal blue sapphire is secured in a six claw open collet, and sits about above an idiosyncratic head. Shaped like a cross between a “V” and a pear drop, the head is set with three transitional cut diamonds and four smaller eight cut diamonds, which leads to a open gallery with scrolling cheniers. The platinum head of the ring sits atop a white gold twist shank. Marvellously, marvellously bonkers.
