These amazing Rainbow Shimmerwing earrings hold a kaleidoscope of colors! The earrings measure 2 1/4 inches in length including the wire. Very versatile and can be worn with any colors. Our Shimmerwings are harvested from the Peruvian Amazon by trained and licensed workers. At the end of their life cycle, butterflies lay their eggs and literally drop from the trees, whereupon their wings are collected and transformed into beautiful jewelry. Each is set in crystal clear acrylic and 925 Sterling Silver, and both utterly unique sides of the wing are visible! Please, however, try to avoid exposure to water; butterflies don't like getting wet, and neither do these earrings. Our Shimmerwings collection is sold by size, shape, and color; while you won't receive the exact wing pictured, it will be as close as Mother Nature allows! Your Shimmerwing is a unique, one-of-a-kind piece of Nature's artwork! We recommend that you use a sterling polishing cloth to keep your sterling silver clean. The polishing cloth is safe for use with all our wonderful jewelry. As with all of our beautiful jewelry, your satisfaction is 100% guaranteed.
