Vintage Cameo Earring

It is silvertone, contrary to the goldtone in the photo. My color balance seems to be off. Clip on marked West Germany. Single earring or can be used as a pin or brooch. I fell in love with this earring when I saw it at an estate sale, years ago. I removed the top button from an ivory silk blouse stitched in a snap and clipped this earring inside the button hole. Instant brooch! It is 1 3/8" in height and 1 1/8" in width. The only wear is to the back of clipping mechanism. Please email for additional photos, maybe I can get the color right this time. I need your zip code to calculate the postage.
