This is a beautiful sterling silver ring with a green glass stone. The ring is simply marked 925. The glass stone is faceted all across the top which gives it a unique look. The ring is a size 8-1/2. The top measures 1/2 of an inch square. There are six silver balls on either side of the stone. The ring is in very good condition but does have a slight age patina and may need cleaning or polishing. Please let me know if you have any questions. Thanks for stopping by.
