A device for enhancing the brilliancy of transparent or translucent stones used in jewelry pieces. A tract assembly with one or more channels is mounted in a conspicuous position of a jewelry piece. One or more carriers holding the stones in a through opening are slidably mounted within the channels. A phosphorescent plate or deposit on the bottom surface of the channel directs visible light to the exposed surface of the moving stones causing refractions with different characteristics as the angle of incidence varies constantly resulting in enhanced brilliancy of the jewelry piece. Plug members are removably mounted to the ends of the channels preventing the carriers from falling off.
