This filligree-like pendant is actually an audio amplifier at its core, and has been painstakingly decorated with dangling diodes and glass resistors. The matching earrings feature the same tiny components as the necklace. The necklace is 16" long with a 3" extension chain and the earring wires are surgical stainless steel with rubber stoppers on the wires. Edition 1/1, and it comes with its own Certificate of Authenticity.
