Cameo clip on earrings

Earrings are in good condition and kept in a clean smoke free home. I don’t know the age of the earrings and they do not have any markings, brand unknown. 7/8” X 1”, black background white cameo, one faces left and one faces right, silver tone. They are in such good condition that so am thinking the company did a remake of a vintage earring. #cameo #cameojewelry
