Introducing a new kind of classic with the Organically Shaped Circle & Treated Freshwater Cultured Pearls Stud Earrings. Each earring features four treated freshwater cultured pearls along one-third of a slightly twisted, organic-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 luster enhancement.
