Wow! This bracelet is so much fun. It moves. It can make noise. It can be worn with an armful or showcased alone. Each silver ball is 16mm and each ring diameter is 7/16". The bracelet weighs a substantial 78.8 grams. The beads test sterling and the rings are magnetic, not sterling. The beads and rings are strung on stretchy nylon. It is in excellent condition. This bracelet dances when you do!
