Tiger's Eye is a chatoyant variety of quartz that exhibits a golden to brownish color, with a silky luster and a striking banded appearance. This effect, known as chatoyancy, is caused by the parallel alignment of fibrous mineral inclusions, typically of croconidolite, within the quartz. Tiger's Eye has a Mohs hardness of 6.5 to 7, making it durable enough for use in jewelry, carvings, and decorative objects. It is primarily found in South Africa, India, and Australia. The gemstone is valued for its unique visual appeal and is often used to create cabochons or beads.
