Vintage Sterling Silver CZ Earrings

NWT unsigned vintage huge 12mm round cubic zirconia pierced stud earrings in sterling silver setting. Still on original padded velvet card but gift box it was likely part of is long gone. Only one previous owner and likely never worn. Sterling has some patina from age and will need a cleaning or polishing or wear them as they are. Great for prom or a bride looking for something old.
