Vintage signed AGATHA Paris silver/blue aurora crystal cocktail ring

Selling two of these- this one is silver (not sure if genuine) with iridescent blue crystal stones; the other has smoky grey stones (separate listing). Bundle both for an even better deal! Very comfortable and well made ring. Size 8. Stamped on base of band as shown. EUC just a bit of tarnish remaining (I cleaned it a bit) and a couple scratches. AGATHA is a jewelry house in Paris. Used to have a store in the Beverly Center in LA and we would use a lot of their designs in TV/film.
