PROBLEM TO BE SOLVED: To provide jewelry, a full eternity ring in particular, which can be processed elaborately, can reduce high initial expenses such as those incurred by molds, and can make gems attached to it shine brighter. SOLUTION: A full eternity ring is manufactured by a grooving process for cutting a multiple number of grooves along the outer periphery parallel to the direction of an axis of a pressurizing prime ring (10) so that a gap is formed between a base (20) and a base (20), a bevel cutting process for cutting a bevel along an end facet formed on both sides of the axial direction of the pressurizing prime ring (10) at each of the bases (20) created by the previous process, a first groove cutting process for cutting grooves along the axial direction of the pressurizing prime ring (10), passing through the center of each base (20), a hole punching process for punching a hole on each base (20), and a second groove cutting process for cutting grooves passing through the center of the bases (20). Four claws are formed on each of the bases (20). COPYRIGHT: (C)2006,JPO&NCIPI
