UNIQUE VINTAGE/ANTIQUE STERLING SILVER, BLACK ONYX AND MARCASITE RING. This ring has 3-D effect. The background is black onyx with a lacy/filigree style overlay with marcasite stones scattered in and around the setting. There are 2 small marcasite stones missing on the very top of the ring but they are not really noticeable unless you look at it VERY close up or with a jeweler's loupe. I have priced this ring accordingly to the missing 2 stones. It measures a little over 1 inch long by 3/4 inch wide.
