vtg AGATHA Paris smoky crystal cocktail ring

Selling two of these- this one is silver (not sure if genuine) with smoky crystals. The other one has iridescent blue stones (separate listing). I cleaned it pretty well but there is a bit of tarnish remaining on the interior of the band. Will come off with a deep clean. Very comfortable and well made ring. Size 7.5. 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.
