Sterling Silver Domed Mexican Screw Back Earrings

Vintage sterling silver domed Mexican screw back earrings. Simple, easy to wear and they go with anything. These vintage earrings would be easy to convert to pierced studs by clipping the screw backs off, giving them a quick sand and gluing sterling posts onto them. They're marked Mexico and sterling. Most likely from the 70s. They measure about 3/4" in diameter and about 1/2" in depth. Have normal patina and wear for age.
