Purple Stone and Silver Toned Decorative Earrings This is for a pre-owned pair of earrings in excellent condition. I am not sure what the purple stone is. The earrings are not marked silver, but an acid test shows trace amounts of silver so they might be silver plate. Selling as costume earrings. Approx. size is 3/4 inch. (see pictures) What you see is what you get. All offers welcome.
