Abstract (en)
Ornamental element with tubular shape formed by a hollow wire (3), made of precious or non-precious metal, having a substantially quadrilateral section and wound helically around a longitudinal axis to form coils arranged in a side-by-side relationship. The ends of the wire are connected by a substantially filiform tie rod (5) extending within said coils along said axis. The method of production comprises winding a bimetallic wire, formed by a layer of precious metal fixed to a non-precious metal, inner core, on a support mandrel (6) of non-precious material, subsequently emptying of the bimetallic wire and removal of the support mandrel by chemical treatment, and connecting the ends of the workpiece by a tie rod (5), such as a small chain, extending within the coils (4). <IMAGE>
