This unique large oval brooch is marked Sterling (silver) on the reverse. It shows three flowers extending upward from two leaves. There is another flower at the base. The closure is a roll over safety clasp. There is a wire at the end of the pin stem. I'm not sure if this is a repair or the way it was designed. However, it is stable and works fine. Very heavy patina. Size is 1 3/4 inches in width by 2 1/4 inches in length.
