Pretty silver pendent, the pen on the back is missing, so it can't worn as a brooch unless you fix but you could add one if you want or wear on a chain.
I think this is silver but it is not marked. It was most likely on the pen that came off. There is a small small bar and a space that you could put a chain threw I tried to show it in the picture. 2 1/4" x 1 1/2" Sold as is no returns
