Magnetic jewelry clasp and article of jewelry

A body-part encircling article of jewelry comprising a main body and a releasable and separable clasp joined to said main body;

• said main body being semi-rigid, non-articulated and having an inherent axial curvature, and comprising a cable, multiple cables, a braid, multiple braids, bundled wires or bundled fibers;
• said clasp having an axial curvature matching the inherent axial curvature of said main body, said clasp comprising a first ferrule, an insertion member extending from said first ferrule, a second ferrule, and a bore within said second ferrule, wherein said insertion member is received within said bore of second ferrule;
• and
• said clasp further comprising magnetic closure means whereby said first ferrule and said second ferrule are releasably joined together;
• whereby said axial curvature of said clasp eliminates lateral strain effects resulting from said inherent axial curvature of said main body, such that the effectiveness of the magnetic closure means joining said first ferrule and said second ferrule is increased, and further such that said main body is not deformed by lateral strain effects.
