This is a 1890's - 1900's small Oval Carved Shell Cameo of Lady's Portrait in a Gold Filled Mount. It was a stickpin at one time and now since the pin is not attached, it would make a nice Cameo pendant, Cameo Ring or could be crafted into a stick pin again. Once a Jeweler has attached a loop to it it can then be hung from a chain. The Carving is very clear and detailed. When you consider the tiny size of this Cameo, it is quite an accomplishment. It is oval in shape, 3/4" by 1/2" and is a real beauty.
