This is a wonderful vintage Art Deco era pin or brooch made of sterling silver and covered with marcasites. It features a design of stylized flowers. It is marked Sterling on the back of one flower. It fastens with a rollover safety catch.
It measures 1 3/4 inches by 1 inch and it is in very nice condition. I don't see any missing marcasites. The silver has some patina and the safety catch is a little stiff but still quite functional.
