Vintage Art Deco Artisan Silver and Onyx Screw Back Earrings

Gorgeous vintage Art Deco style Mexico Artisan sterling silver and onyx earrings from my grandmother's estate. These beauties are circa 1950's and are sterling silver and black onyx. They have screw backs that may be tightened as much as you like. I have worn these quite a few times over the years and just can't keep everything that I have so would like to put these out there for someone else to enjoy. I am not able to identify a hallmark and there is a close up in one of the pictures. My grandparents traveled to Mexico from San Antonio quite a bit and did a lot of shopping. For each piece I am listing, there are so many more that I am keeping for myself. These are in beautiful vintage condition! Please see pictures for details. Reasonable offers are welcome! #silver #mexico #artdeco #artisan #vintage #antique #art #texas #western #handmade #handcrafted
