Vintage 925 Sterling Silver Mexico Earrings With Red Stones Posts Pierced Ears. Note; butterfly backs are not the original backs and are not sterling silver. I have not been able to identify the stones. One earring’s stone has definite black veining. Any white marks on stone in photos are from the lighting and are not imperfections or scratches. Marked Mexico 925. Good pre-owned condition. Silver shows wear aka patina. Only earrings included. Any other item in photos is not part of product and is not for sale.
