DESIGNER SILVER MEXICAN PIERCED EARRINGS W/ GOLD TRIM

These are designer Mexican silver earrings for pierced ears with a gold chain like trim. It is marked but I am only able to make out the following "925 Mexico". ATON are 4 other letters plus that are marked on the back. They measure each 1 5/8 inches by 1 inche. They are in excellent condition. I am unable to accurately date these earrings. I have also listed a similar designer pin with the same mark that is not totally readable.
