This is an original old pin studded with marcasites in an elaborate scrolled metal frame. An elongated black onyx stone measures one inch long. The pin itself measures 2 inches by 1 ¼ inch. The clasp is a very old style – a c clasp. Machine testing by my jeweler revealed the pin is unmarked Sterling. Condition is very good with patina. It’s a wonderful early pin that dates to the pre 1905 era.
