Vintage CZ Cocktail Ring

Very cute, dainty and elegant CZ ring. I suspect this ring is plated with sterling silver but as it is not marked in anyway, I'm not certain. However, it has not turned my finger green with normal wear. Please see photos for wear and patina. I am willing to hand polish &/or deep clean the piece at your request, after check out. *REASONABLE* offers considered. Low balling will be ignored.
