ABSTRACT:
A piece of jewelry comprises one or more half-tubular members which have a main curvature lying in the primary plane of the jewelry. The half-tubular member has an outer, highly polished concave surface and an inner, highly polished convex surface where both surfaces lie or extend in the primary plane. This produces the illusion that the half-tubular members are in fact fully tubular and thus, produces jewelry that has a heavier look and impression even though it is made with half the precious metal.
