Canyons and Crystals Eyeglass / Sunglass Chain. Red Jasper beads look as though they have been freshly mined from some of the colorful veins seen at the Grand Canyon, but these rustic matte beauties came from Australia! Mixed with tiny, fire polished crimson crystals and antiqued gold tone beads, this 27 inch long glasses chain exudes rugged charm. Adjustable stretch ends fit most frames.
