This is a unique pair of clip earrings. The earrings have an inlaid design with faux turquoise, lapis and jade. I am not certain what the earrings are made of but it looks like enamel. The earrings are not marked. They measure 1-1/8 inches square. The earrings are in very good condition and appear to have been gently worn, if at all. They may need cleaning or polishing. Please let me know if you have any questions. Thanks for stopping by.
