Glass is hand wrapped in coloured wire and hung on metal thread. Clasp is also handmade to match the wire used to wrap the glass. The glass is secured in place so it will not fall out. Each piece measures approx. 1 inch. Your piece may differ from the one pictured here, as each piece of glass is different. The necklace is approx. 16? long, but can be made longer or shorter at your request. The wire comes in many colours.
