This is an 1880's or 1890's fob locket, or locket originally worn as a watch fob. The front features a hand-carved black onyx intaglio (reverse cameo) of a soldier with helmet. The round onyx intaglio is bezel-set. There is a fancy raised design around the edge of the intaglio, and the locket itself has a scalloped shape. The back of the locket has a raised sickle-moon with fancy work on each side. The locket opens at the top with a period tube hinge. Included with, but not original to, is an 18" rose-gold-filled chain. There are no marks. The locket is 3/4" in diameter and 1/4" thick. It is in excellent original condition.
