Vintage Rhinestone Clip On Earrings

Vintage clip-on rhinestone earrings. The earrings have a unique shape featuring a larger rhinestone center. The earrings have no signature on the backside. Three of the rhinestones on the outer edge of one earring have discolored to a darker color. Most likely they need a professional cleaning to brighten them back up. All the rhinestones have a prong setting.
