This is a vintage sterling silver brooch. It is simply marked 925. The brooch has prong set real amethysts and marcasites. The brooch looks like a spray of flowers tied with a bow. It measures 1-3/8 inches long and 1 inch wide. It weighs 4.9 grams. The brooch is in very good condition with no missing stones. However, it does have an age patina and may need cleaning or polishing. Please let me know if you have any questions. Thanks for stopping by.
