Cameo pierced dangling earrings NWOT

Jewelry is kept in a clean smoke free home. These earrings have been around for a while but not used. No brand noted. These earrings are silver tone and do attract to a magnet so not silver, the backs are a solid silver tone, front is a 4 mm round silver ball stud with a black/off-white cameo dangling 16 mm, the cameo itself is 11 mm. There is a chain link connecting the cameo to the stud. Super cute sitting in silver tone frame too.
