Abstract
A chain link of hollow construction and substantially uniform thickness, for intertwining with other chain links to form a jewelry chain, has a non-annular cross-section throughout the link with the cross-section being symmetric along a centerline plane through said cross-section. The cross-sectional shape of the link preferably has on each side of the centerline plane, at least two sides that meet at a point of inflection. On each side of the centerline plane, at least one side preferably converges toward said centerline plane. A reduction in manufacturing costs and precious metal used to form the links and therefore the chain is realized by using a non-annular cross-section having such constructional qualities.
