A hollow ring design which may be formed by stamping a shank and stamping a top piece is provided. The shank is formed with a comfort fit, such as a convex configuration, along its inside surface and with a non-planar recess, such as a concave, rectangular or square hollow configuration, at least along a portion of its outside surface. A top piece is also stamped along its inside surface and is thus formed with non-planar recess, such as a concave, rectangular or square hollow configuration, opposite that of the recess of the shank. The top piece is configured and sized to fit onto the shank without any need to force fit one piece to the other, while at the same time forming an arcuate channel inside the ring to reduce the cost of materials.
