These Julie Vos earrings are really versatile. You can wear them as a single hoop or as a double hoop, depending on your style. To keep them in top condition, make sure to avoid getting them in contact with things like lotion, perfume, make - up or harsh cleaning products. Also, take them off before you shower, swim, exercise or wash your hands. This will help maintain their beautiful luster. They are made with 24k gold plate over nickel - free brass and are sealed to prevent tarnish, so with proper care, they'll last a long time.
