I've had this piece in my collection for some time. Beautiful antique ring. Authentic sterling silver Arts and Crafts ring (c. 1900). This one has the most interesting crackle glass cabochon of glowing blues + greens. Looks like a little galaxy on your finger. In addition to the beautiful center cabochon, the shoulders feature an autumnal leave design. Gorgeous, unique piece. Marked "sterling." Size 5.5, sizable.
