Vintage Goldtone Hand Carved Cameo Clip On Earrings

Vintage goldtone clip on earrings.
The cameos are hand carved, but they are not shell. They sound like glass, but they may be some sort of plastic.
Earrings are not hallmarked.
They measure 3/4" tall and a little more than 1/2" wide.
Clips work well. They have not been cleaned or polished.
Together they weigh 8.3 grams.
Great vintage condition.
