Circa 1930's sterling silver filigree black and white glass cameo ring. Intricately detailed filigree work perfectly surrounds the glass cameo. I have never seen anything like this lovely ring. The filigree work frames the cameo, with ornate decoration on all edges, even side and back detail. Condition is excellent. Marked "Sterling" inside ring shank. Ring is size 5 3/4, top measures 7/8" by 5/8" across.
