Introducing a new kind of classic with the Shaped Circle & Treated Freshwater Cultured Pearls Stud Earrings. Each earring features four treated freshwater cultured Pearls along one-third of a slightly twisted, looking sterling silver oval with varying thickness. Each treated freshwater cultured Pearl is unique and can vary in size and color; normal wear and tear may occur with this material. Our freshwater cultured Pearls are treated with bleaching and lustre enhancement.
