Diamond and Sapphire Plaque Ring


This Art Deco platinum plaque ring, dating from the 1920s, is set bezel-set with a nearly one-carat, oval-cut diamond, old European-cut diamonds, and sapphires. Designed as a rectangular plaque with open gallery and incised accents, the ring centers an old oval-cut diamond within a double frame of old European-cut diamonds, with calibré-cut sapphire highlights and shoulders. With its unusual central diamond highlighted by glowing blue sapphires, this impeccable ring with its interlinked geometric motifs, gracefully elongates and beautifies the finger.
