This delicate shell cameo features a lovely lady who appears to be from the 1920's. She has a gathered dress with a floral clip on the shoulder. She has great depth and is intricately carved. She sits in a filigree setting. the setting appears to be sterling as it is tarnished and will shine with polishing but there is no mark that I can find. The pin measures 1" x 1 1/2" and has a c-clasp.
