Abstract

A jewelry chain section and a method of forming the same having a spiral, twisted appearance, involves the winding of a wire on a support and the controlled manipulation of such wound wire during or after removal from the support. The wound wire comprises individual spirals that are twisted relative to each other, such that the individual spirals appear in a staggered formation, with the appearance of a chain section being varied by the number of spirals that are twisted at a particular time and the extent or angular dimension of the rotation imparted to such spirals.
