Roughly oval-shaped brass has a "spot hammered" surface. The circle of brass surrounding the amethyst- colored rhinestone appears to have silver gilt over it giving it a slightly different color. Two triangular cutouts are filled by the filigree wire work. There are 3 half-domes, brass, set in dotted circles on each side. The faceted rhinestone is bezel set with two leaves framing it top and bottom. There is a round hinge and c clasp. This pin reflects Arts and Crafts style. 1 9/16" long. 1 1/16" wide
