This is a large sterling silver pendant with an amber cabochon. The pendant is marked 925. I do not know if the amber is real or synthetic. It does have a lot of inclusions inside. The pendant measures 2 inches long and 1-1/2 inches wide. It weighs 20.3 grams. The pendant is in very good condition but may need cleaning or polishing. Please let me know if you have any questions. Thanks for stopping by.
