Fiber Optic Glass
This a synthetic (man-made) stone is composed of a substance known as Ulexite. Ulexite is spun glass fibers fused together. Any stone that displays the cat's eye effect, including Fiber Optic Cat's Eye, Tiger, Eye, and Chrysocolla to name a few, is said to have chatoyancy, which is an optical reflectance effect seen in certain gemstones. Coined from the French "œil de chat", meaning "cat's eye", chatoyancy arises either from the fibrous structure of a material, as in tiger's eye quartz, or from fibrous inclusions or cavities within the stone,
Even though Fiber Optic Glass is man-made, it still contains the chemical properties of some types of natural glass (primarily Quartz), so it is said to posses the same metaphysical attributes. Fiber Optic Glass brings serene happiness, it stimulates intuition and enhances awareness. It is considered to be lucky for gamblers and protects from the Evil Eye.
