I believe this is gold washed silver, there is a mark on the bottom backside but I cannot make it out.

See photos for this detail.

The frame is primitive and crudely made but the shell cameo is lovely.

It measures 1 1/8" across and 1 3/8" tall. She is a left facing beauty!

It has an hidden pendant loop in the back. The pin works fine.

Needs a cleaning.
