This is a pair of vintage Mexican sterling silver and inlaid abalone screwback earrings. The earrings are signed but the mark is only partially visible. It is behind the screw mechanism and I am unable to read it. The earrings are shaped like curved arrows. They measure 1 inch long. The earrings are in very good condition but do have an age patina and may need additional cleaning or polishing. Please let me know if you have any questions. Thanks for stopping by.
