What does that mean it "it is a pin style cameo"? Does it not have the pin in the back? Does it have a place to put it on a chain, if there is no pin? Thank you.
It may be one of those pendant brooches. So you can wear it on a chain or attach it to sweater. It looks to have a bail for hanging, but not sure with my eye sight. I have many similar pieces and they're nice:)
