These intricate silver and turquoise & onyx screw back earrings are a beautiful representation of 1930's - 1940's Mexican silver craftsmanship and each feature a large onyx center stone with two small turquoise stones. No maker hallmarks are visible, but they are stamped with "Silver Mexico" on one, and what may have been a maker mark that has worn with age on the other.
In great vintage condition with wear and patina consistent with age, all stones are present and in good condition.
