Bead, cat's eye glass (fiber optic glass), opaque black, 16x6mm teardrop, quality grade. Sold per 15-1/2" to 16" strand.

Fiber optic glass cat's eye beads get their name from the way they refract light, resembling the oblong center of a cat's eye. These beads feature an attractive color shift and inner glow that will complement a variety of jewelry designs. Sizes, shapes and colors may vary. Items are made with solid color glass, which means the base color of the glass is saturated throughout the object and will not fade or rub off over time.
