I honestly don't know. It was my daughters . I recently found a box of jewelry she had left and other than a couple chains she gave me permission to auction off the items. She mentioned most where from the gold mart where she would spend most of her earnings.Considering the age and how good it looks I would guess at the very least it is plated but without taking it to a jeweler I can't be sure.
only thing I can see stamped is Medina- it is heavy for a small piece so I know it is solid metal. My asking bid of 100 just covers us shipping, so no matter what it is a great win since you would be getting the item for free unless the bid goes up which I hope it does. I think the people who have won my auctions have gotten the better end of the deal for the most part.
