I believe this piece is Gutta-Percha on the carved relief - the bottom section appears to be glass. It is set into 4 very pronounced prongs. The oval frame was pehaps once a gold washed. The backside is a strong the roll over clasp and crudly crafted I feel. I hope all my pictures are clear and accurate. This piece measures 1.75" tall. I have a large ollection of cameos - if your a fan check back now and then to see what I've added.
Will ship via USPO with delivery tracking.
