This was my grandmothers, she wore it on a hat and as a lapel pin. I think it is circa 1930's. It is a beautiful small period Art Deco , silver and black enamel circular brooch. This is in wonderful condition , the banded black enamel in great condition ( no chips ) .It has 8 set crystals . Approx 7/8" X 7/8" 1/8" thick No markings that I can see, therefore Im describing it as silver tone. Security clasp
