Oscar de la Renta Hammered Gold Clip On Earrings Vintage Crescent Used Tarnished

*** please see all photos and read full description *** Pre owned vintage condition, clip on style, two Oscar de la Renta markings on each earring. As shown in photos there is significant tarnish on one earring. I'm not a jewelry aficionado so I don't know if it can be fixed or repaired, selling with this flaw in mind.
