This is a pair of vintage Mexican screwback earrings. The signature is hard to read but it looks like they are signed AS with a flower mark, 925 and HECHO EN MEXICO. I can also read part of the word STERLING. The earrings have both sterling silver and copper. They measure 1 inch in diameter and weigh 11.8 grams. The earrings are in very good condition but do have a heavy age patina and may need cleaning or polishing. Please let me know if you have any questions. Thanks for stopping by.
