  • Jewelry lighting device
    Patent number: 5519591
    Abstract: A lighting device mounted within a jewelry setting which is directed at a facet of a gemstone to increase the brilliance and brightness of the gemstone. The lighting means is a low dispersion, focused beam of light which is directed at a facet of a gemstone so that the gemstone captures the light. In the preferred embodiment, the lighting source is radioluminescent or electroluminescent and uses various focusing means to focus the light from the lighting means. Fiber optic material may be used to direct light at the gemstone. The fiber optic material may contain dyes which absorb ambient light and cause the light to be directed in desired wave lengths at the gemstone. The fiber optic material may absorb light from the lighting means, as well as ambient light, to provide additional illumination in relatively high ambient light situations.
