Cameo Vintage Brooch

A very pretty cameo with a lady head outline in a mother of pearl look. I am more inclined to think it an irridescent glass, beautifully moulded and set in an oval shaped black frame surrounded with faux pearls and small black beads.  It is quite large at 6.5 x 5.5cms with a firm roll over safety clasp to the back. In excellent condition with only a little wear to the back commensurate with age...likely a l960's-1970's piece - from an estate sale USA. Impressive and striking accessory gift boxed by Vintageonline.
