Gorgeous Mexican Montero Taxco Opal Inlay Earrings

These gorgeous earrings are vintage Mexican Montero Taxco and made with .925 Sterling Silver and opal inlay! .925 Sterling Silver stamped on the back as shown in the photos. There is some patina build up, which can be left for an aged wear or polished shiny again. They do have 2 slightly different backings, though I can replace with a matching set if requested before shipping! Each earring is roughly 1 inch long in length. Not sure on pricing, so please feel free to send any offer you feel is reasonable!
