This is a pair of silver tone and marcasite pierced earrings. They are not marked and I do not know who made them. There is a stamped design on the back of the earrings. The earrings measure 1-3/8 inches long. They 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.
