The necklace is very unusual. It has been designed so one part can be worn at the front and the other part is worn down your back.
It is one continual fine chain approx a meter in length. At one end it has buzz sitting on a very large hexagon the other end has buzz suspended from smaller hexane.
The clever part is in the middle of the chain this is the clasp. It is made of silver with a rubber inside, the chain runs through the rubber. This clasp can then be moved backwards and forward along the chain so you can have the length you desire either at the front or the back.
The necklace is made of Sterling Silver, with rubber tube within the clasp.
