Abstract
An article of illuminated jewelry has a substantially planar, radial array of fiber optic filaments organized around a common light source and secured at an end proximate the light source by an annular plastic matrix. In a preferred form, the matrix is an epoxy resin ring and the free ends of the optical fibers are angled up to direct the transmitted light away from a person wearing the jewelry and towards a viewer. The free fiber ends can extend beyond the edge of a decorative body or shield of the jewelry, or project through apertures formed therein. The tips preferably form a decorative pattern or otherwise contribute to the aesthetic appeal of the piece of jewelry. In one form, two or more arrays ar stacked to increase the density of the light emitting fibers. A self-contained battery and switch arrangement power and control the light source.
