This beautiful pendant is made from the wing of a REAL moth, the Sunset Moth. The pendant is copper and is 1" in diameter. The chain is also copper, and is available in 18" or 24" lengths. The Blue Mountain Swallowtail (Papilio ulysses)is a large swallowtail butterfly of Australasia (a region comprised of Australia, New Zealand, the island of New Guinea, and neighboring islands in the Pacific Ocean). It has a wingspan of up to 5.5 inches. This butterfly is used as an emblem of tourism in Queensland, Australia. When in flight, the butterfly can be seen hundreds of feet away as sudden bright blue flashes. PLEASE NOTE Your necklace is handmade to order. While your necklace will be nearly identical to those pictured, because no two butterfly wings are identical, there will be some very slight variation (including color) from those shown in the photographs. HOW MY BUTTERFLIES ARE OBTAINED No butterflies are ever harmed or killed in the making of my jewelry. I obtain my butterflies from butterfly farms and conservatories after they have been allowed to live their full lifespan and have died naturally. Butterflies are natural works of art! By creating jewelry using real butterfly wings, these amazing works of art can by preserved and enjoyed, even after the butterflies have passed on naturally. CARE & CLEANING INSTRUCTIONS I spend a great deal of time, effort, and love creating each piece of jewelry. However, because of the delicate nature of the wings, my jewelry is NOT waterproof. Please remove before showering or swimming. To clean, gently wipe with a baby wipe. Avoid detergents and other harsh chemicals as well as traditional jewelry cleaners.
