This sparkling marcasite ring dates from the art deco era. The sterling silver ring is marked 925 with a partially obscured maker's mark on the inside of the shank. The top is lightly domed with a sunflower in the center encircled with a scalloped border. The silver is textured and studded with sparkling marcasites. The top measures approximately 5/8 inches in diameter and the ring fits size 7 3/4. It is in excellent condition and has been lightly polished retaining some of the dark age related patina that could be removed if desired.
