This is a Victorian very old necklace, it has a shell cameo on a sterling(marked on spring ring)chain and I think the the frame of the cameo is sterling. The necklace is 16 inches long with 2 inch drop. I will leave the cleaning to you, but will include a cleaning cloth. It will also be in a velvet bag and gift box. The cameo and the frame is attached to a Y at the sterling chain. This has old marcasites and none are missing. It would make a great gift! To you from Kansas a lovely cameo.
