Antique Vtg Black Flower Mourning Brooch w/ C-clasp AS IS floral swirl pin

Beautiful vintage or antique black floral mourning brooch. A swirly flower design. Made of metal with some sort of plastic-like overlay. A lot of the overlay is missing or damage. The back appears to be black enameled. There is a crude C clasp (that does not hold the pin) and the pin does have some bending. Please examine all photos closely to see wear/damages. Approx. 1 3/4"
