This cloisonné enamel and crystal necklace and fitted case was a proof-of-concept based on several of Victorian art nouveau pieces. The butterfly is glass enamel on copper with fine silver foil and cloisonné wire. The chain and wire work are all sterling silver, and the crystals are 4mm Swarovski bicone beads. The case is covered in black mulberry paper and faux-silver (aluminum) leaf, and lined with black velvet. The inner case is fitted precisely to this necklace.
