PROBLEM TO BE SOLVED: To raise a value added by allowing diamond emitting light by receiving ultraviolet rays to form a prescribed motif. SOLUTION: A ring 11 is provided with a collet 2 over the ring 1 and plural gemstones 3 are fixed at prescribed intervals at the collet 2. As all or a part of the plural gemstones 3, diamonds 5 emitting-light at the time of receiving irradiation of ultraviolet rays are used. Concerning these diamonds 4 emitting light at the time of receiving ultraviolet rays, matters emitting light at the time of receiving the irradiation of ultraviolet rays coexist in general diamonds and these ones are selected and used properly. The diamonds 4 emitting light at the time of receiving the irradiation of ultraviolet rays are plurally arrayed on the collet 2 of the ring with the other gemstones 5. Then, a prescribed motif such as an alphabet A is formed with the light-emitting diamonds 4. This constitution can be applied to the decolating part of kinds of accessories such as a bracelet in addition to a ring and the prescribed motif is formed with the light emitting diamond 4 to raise its added value.
