This is a pair of vintage sterling silver screw back earrings. The earrings are signed STERLING, HECHO EN MEXICO and have an Eagle 83 mark. The earrings have some type of fossilized stone in the center. The stone catches the light in an interesting way. The stone is bezel set. The earrings measure 1-1/8 inches long. They are in very good condition but do have an age patina and may need cleaning or polishing. Please let me know if you have any questions. Thanks for stopping by.
