This is a very delicate small cameo necklace. Comes with a 16 inch chain. It has a makers mark on the back "rainbow" and is stamped G.F. for gold filled. Size is .81x.63 inches. So it is almost exactly the same height as the diameter of a nickel. Nice piece. Age I put as probably 1950's-1960's make a great gift. Comes gift boxed.
