Butterflies are beautiful as evidenced with this pair of stunning Shimmerwing earrings. Mute Green and Black are the colors on the front while earthy colors of cream, green and brown are seen on the back. They measure 1 inches in length not including the hook. 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 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 does this jewelry. 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.
