Tiger’s eye is a translucent variety of quartz, with a golden-yellow color. It exhibits a characteristic linear iridescence like a moving reflection. These lines are golden and brown in color and retain the fibrous structure of crocidolite. This very characteristic optical effect is known by the French word chatoyancy, which means “cat’s eye” and symbolizes the union of the Earth with the Sun. Tiger’s eye is considered to promote decision-making and self-confidence. It is encountered in the USA, South Africa, Namibia, and Brazil.
