Vintage Cameo Brooch

This is a vintage cameo brooch. It features an ivory colored carving of a woman’s face in profile which is elevated on the framework of a black background. The raised relief image seems to be one that is featured on many styles of brooches. The uniqueness of this piece is the setting. An online search of brooches did not result in any others with the setting in a heart design exactly like this one. The color is gold but cannot specify what type of metal. The measurements of the brooch are in the photos. It is in very good condition. Comes from a smoke free home.
