This is a vintage combination brooch and pendant. It is simply marked 925. The brooch has a beautiful mother of pearl cabachon in the center. The mother of pearl seems to almost glow. There are also old style prong set marcasites. The bail is a wonderful shape and also has a marcasite on it. The brooch measures 1-3/4 inches long. I believe that the pin might have been added at a later date. The brooch is in very good condition but does have a heavy age patina and may need cleaning or polishing. Please let me know if you have any questions. Thanks for stopping by.
