Rare 19th century mother of pearl hand carved cameo brooch. Although one may think it is Biedermeier, my evaluation is that it is slightly later neoclassical era, circa 1865-1885, more like the style and look of the Statue of Liberty! Instead of the more common 2 color shallow water conch shell cameo, deep sea nautilus mother of pearl is used and the cameo is created from the different layers of texture in the shell pearl. A very elegant and unusual addition to any cameo collection. The austere simplicity of the plain mount makes it look great worn with modern clothing and against black. Faintly marked: STERLING on the top back rim of the mounting. Measures 1 inch by 1.25 inches.
