This is a lovely brooch. At the center of it is a fairly 3 dimensional white Angel skin Coral Cameo. The Cameo is surrounded by a mosaic frame which is set into silver. The silver acid test to be at least 800 silver. It measures 1inch in diameter. It has a replacement clasp. It now has a safety clasp. It probably had to "C"clasp before the change was made. It should make a lovely addition to your collection.
