Enjoy the natural beauty of a real butterfly necklace! This butterflies latin name is Graphium Sarpedon and it comes from South and East Asia but it is commonly referred to as a "Blue Bottle Butterfly". I have preserved this butterfly in several layers of hand painted resin. The resin is clear so what you see are the natural colors of the butterfly. This resin also has a wonderful effect of turning the butterfly semi-translucent giving it an appearance much like stained glass. The wing span of this beautiful butterfly is 3 3/8", making for a intriguing statement. This real butterfly pendant comes on an 18 inch 1.5mm black leather cord with a small chain extension and an easy to use lobster clasp. It will make for you a definite conversation piece that will attract you plenty of attention!
