ABSTRACT:
A method of manufacturing jewelry and a chain article formed therefrom that results in a product substantially lighter than its solid counterpart. A length of wire mesh or woven wire type of “fabric” having a hollow seamed wire with a non-precious core of a width and length corresponding generally to the proportions of the jewelry chain to be created is provided. The non-precious core is then removed by one of many methods. Then, a series of hollow link sections are received on the length of wire mesh such that the interior surfaces of the links surround the mesh. The links are arranged in an end-to-end abutting relationship upon the mesh until the length of chain desired is reached. Alternatively, a spiral resembling a spring may be used. Upper and lower die members are brought into contact with the preformed chain and forced there against with a magnitude of pressure and for a duration of time sufficient to deform the links or spiral and bring the inner surfaces thereof into at least partial engagement with the mesh.
