Vintage Shell Cameo Brooch

This piece is amazing. I am selling it for a friend who is a jeweler. It is a vintage piece that we are assuming came from the 50s. He acquired it from a friend of his who lived in New York City for 3 decades. It was her mother’s. It is gold plated and the plating is in fantastic condition. They just don’t do it like that anymore. It is 2 inches tall and 1.5 inches wide.
