This is a vintage Art Nouveau silver brooch. It looks like it might be sterling silver but it has not been tested. There are no markings on the brooch. The brooch has two flowers in the center and has a C clasp. It measures 1-1/2 inches in diameter. The brooch is in good condition but does have an age patina and may need cleaning or polishing. Please let me know if you have any questions. Thanks for stopping by.
