The first photo is enlarged to show details. Olive commons. Florida brooch. I'm not sure if the pin/clasp was replaced or if this is the original. I've seen others w the same "nail" looking type clasp. Measures approx 3/4 inch X 1/2 inch. Signed on lower right side. Will be sent in the box shown in last photo. Box has minor scratches.
