Abstract
A jewelry item is provided to include a ring-shaped spring and a ring-shaped chain. The ring-shaped chain has a plurality of chain links, each of which is slidably attached to the ring-shaped spring. Each chain link has a plate with a first surface facing the spring and a second surface opposite to the first surface. Each chain link further has a seat and a hook opposite to each other. The hook is inserted into a seat of a subsequent chain link so as to lock the chain links to each other while allowing the chain links to reversibly slide from a compressed position to an expanded position with respect to each other.
