This is a lovely antique Victorian era pin set with a mother of pearl cameo. The setting is very ornate and it has a gold colored finish. Most likely it is gold filled, but it is unmarked and I have not tested it. It fastens with a c catch.
It measures 2 inches by 1 1/4 inches and it is in good condition. The cameo is a little loose in the setting, but it is secure. The metal on the back is discolored and the pin stem has some rust.
