This sterling silver diamond-cut oval cable chain features a movable silicone-lined bead that allows you to adjust the chain to any length up to 22 (maximum). The end of the chain is finished with a round bead accent. The most common chain style, cable chains are formed by simply connecting single links perpendicularly end to end. Links may be round, oval or other shapes. Diamond-cut versions have facets precision-cut into the links with diamond-tipped tools. The facets are then polished to enhance the light-reflecting properties of the link surfaces.
