Small Victorian pin. Measures about 1.5 inches long. Simple C-clasp. indicative of a piece from the late 1800's . This came to me with a group of other items. I do not know the metal or the stone. I am going to guess it is gold filled, only because it looks more gold then brass, Also is in really great condition. Brass would be dark and tarnished. A magnet does not stick to it ...so it has no iron/steel in it. Not marked.
