This measures 2 7/8 inches by 1 7/8 inches. Made by G.C. Hudson Co. North Attleboro, MA . Early 1900's. Marked G.C.H on the 'C' clasp. This is silver and silver plate where the flowers are. There is a break in the frame 9see photo) that is visible but does not detract from the beauty of this old brooch. It is heavy. The center is most likely glass and has not been tested.
