This beautiful pendant is made from the wing of a real butterfly, the Emerald Swallowtail. The pendant is antique silver and is 1" x 1.25" in diameter. The chain is also antique silver, and is available in 18" or 24" lengths. This necklace would be a unique gift for someone with a May birthday. The Emerald Swallowtail (Papilio palinurus), also referred to as the Emerald Peacock or Green-banded Peacock, is a butterfly native to southeast Asia. It has a wingspan reaching about 3.1–3.9 inches. The upper sides of the wings are covered by a powder of green scales and the background vary from dark greenish to black, with broad bright emerald green metallic bands. The flight of these butterflies is swift and quite fast. 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.
