ABSTRACT:
Thin metal foil jewelry is manufactured by a process which includes initially crimping the foil randomly, and then again crimping the foil while rotating the crimp to bring the sides of the crimp out of the plane of the foil to form peaks and valleys and to cause the foil to assume an arcuate shape. The peaks and valleys and the arcuate shape add rigidity to the thin foil and resist deformation. The jewelry can be further processed to form a bead on the periphery of the foil and/or holes which are formed within the foil to add further rigidity to the foil and to change its appearance.
