Art Deco pendant, onyx plaque with a prominent rose cut diamond Circa 1930

Art Deco pendant, circa 1930, in 18K white gold, centred on an octagonal onyx plaque with a prominent rose cut diamond in a milgrain bezel. The slender, stepped suspension is set with further rose cut diamonds and small rose cut diamonds, giving a crisp play of light against the black ground. Neat, architectural and quietly glamorous, it wears like a small piece of the Jazz Age.
