These are a simply gorgeous and fairly heavy pair of genuine, vintage Navajo earrings made by the well known artist Sharon Cisco. These are quite unusual and feature mother-of-pearl and a detailed silver backing. Although they are not marked silver, they certainly are silver. I have chosen to keep on the patina of age that they have. The SC is clearly stamped on the back of each earring. Incredible. Very wearable condition. Original backs are gone.
