Abstract

A finger ring is made by a method involving the steps of drawing precious metal through a die (8) and winding the length directly onto a former (10), to produce a helix (4). Individual ring-shaped pieces are then cut from the helix and the ends of each piece are secured together, either directly or through the intermediary of a head, without any significant quantity of heat being input to the metal subsequent to the drawing operation. In this way superior strength characteristics are obtained, rendering the ring less liable to damage by undesired deformation. <IMAGE>
