VINTAGE STERLING SILVER & TURQUOISE CABACHON PIERCED EARRINGS

I purchased these pretty sterling silver & turquoise cabachon style pierced earrings on a trip out west, close to 40 yrs ago. I bought them when visiting an Indian reservation in Arizona, and was told the turquoise was from the Sleeping Beauty mine. The earrings are a pierced style with post backs & butterfly closures & are engraved with a sun design all around the edges. The backs have a flat finish. The earrings measure approximately 1" in diameter & although they have no markings, I assure you they are sterling & have been acid tested. Please note that one of the posts looks to have a slight bend, but nothing that is very noticeable, or that would affect the wear. Thank you for viewing my listing! Reasonable offers are always considered. No lowball offers, please.
