PROBLEM TO BE SOLVED: To provide a combination ring capable of exhibiting the integration in the design and structure between combined rings by encasing one ring in the other ring, and a method of manufacturing the combination ring. SOLUTION: The inner radius Rin1, the thickness T1 and the width W1 of an outer ring 101, and the inner radius Rin2 and the width W2 of an inner ring 102 are determined in steps 201 and 203. Next, the size of clearance CLR is determined according to the width W2 of the inner ring 102 in the step 205. Then, the thickness T2 of the inner ring 102 is determined based on the inner radii Rin1 and Rin2, the thickness T1, the widths W1 and W2, and the clearance CLR in the step 207. Finally, ornament parts 101d and 102d are engraved in the outer ring 101 and the inner ring 102 whose sizes have been adjusted. COPYRIGHT: (C)2005,JPO&NCIPI
