This beautiful pocket watch style pendant is made from the wings of a real butterfly, the Blue Morpho. The wing sits beneath a glass cabochon measuring 30mm round (approximately 1.2"). The necklace is a faux pocket watch, not a real working pocket watch. Both the pendant chain are a beautiful antique brass. The chain is available in 24" or 30" length. The Menelaus Blue Morpho (Morpho menelaus) is an iridescent tropical butterfly of Central and South America. It has a wing span up to 5.9 inches. The males are very territorial and use their bright blue wings to scare off other males. Intricate patterns of scales on the underside of their hind wings create an illusion of large staring vertebrate eyes, complete with pupils and irises. It is thought that these intricate eyespots are used by the butterfly to startle or otherwise confuse hungry predators such as birds or lizards. 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 may be some slight variation (including slight color variation) 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. While my pieces are water resistant, because of the delicate nature of the wings, they are 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.
