The hallmark "Silver 800" (European silver) is on the back frame, so the frame is made of silver. It depicts a very beautiful profile of a woman. It has a clasp on top, so it can be used as a brooch or a pendant top. I found this while cleaning out my grandmother's house, so I don't know where it was purchased, and there is no certificate, so I'm selling it at a low price. Please understand that this is a used item before purchasing. Cameo brooch Cameo pendant Shell cameo brooch
