I genuinely enjoy the hypnotic effect of this real butterfly wing necklace. With its field of mottled browns and subdued blacks, it is curiously illuminated by an unwavering "eye spot" that holds the viewers attention. The species name for this unusual beauty is Caligo Telamonius. It is better known as the "Giant Owl" butterfly which can be natively found from southern Mexico down into Nicaragua. I have sandwiched this choice selection of wing between two pieces of glass that I have cut by hand. Then using copper foil I hold it all together so that I can skillfully finish with Lead Free Solder. This mesmerizing pendants measurements are 5/8" wide by 1 1/8" tall, making for an enticing charm. It comes on an 18 inch 1.5mm black leather cord with a small chain extension and an easy to use lobster clasp. A natural beauty to behold, you will find this real butterfly necklace simply spellbinding.
