Our version of a very popular stretchy bracelet out of London features an 'infinite' number of 7mm sterling silver rings strung on two individually knotted pieces of elastic. If one strand breaks, the other will maintain all of the silver rings. A 4mm sterling silver beaded bracelet sits within the rings to keep them 'straight'. The standard bracelet size is 6¾" and is designed to fit slightly snugly around the wrist, without extending onto the hand. To determine your size, measure your wrist circumference using a piece of string, then add ¾" for your ideal bracelet length.
