Our carved shell cameo 10K pendant displays beautifully on it's dramatic opera length chain. It can be worn as a brooch pinned up high allowing the 35'' gold fill chain to festoon around it. I believe this gracious lady to be Demeter (Ceres), goddess of the harvest with stalks of wheat in her hair. The cameo brooch is a generous size at 2'' x 1-1/2''.It is bezel set with a twisted rope border. It's pin stick appears to be a replacement and is not gold. I would date this piece at least back to 1920 but quite possibly the turn of the century. Age appropriate wear.
