PROBLEM TO BE SOLVED: To provide a manufacturing method for a ring which effectively manufactures the ring with a high yield, in which the design of the ring more strongly recalls a concept that the ring has been manufactured of one and the same material.SOLUTION: A ring 2 for men and a ring 3 for women are obtained by separating one material. A convex part 2a and a convex part 2b which are projected from the outer peripheral surface of the ring generated by separation are formed on the ring 2 for men, and a convex part 3a and a convex part 3b, which are projected from the outer peripheral surface of the ring generated by the separation are formed on the ring 3 for women. Thus, an appearance image that the convex part 2a and the convex part 3a, and the convex part 2b and the convex part 3b are obtained by separation and manufactured of one and the same material is given to the ring 2 for men and the ring 3 for women. |
