Tiger’s eye

Tiger’s eye (tigers eye, tiger eye, tiger iron) is a member of the quartz group of chalcedonies. It is one of the chatoyant gemstones. Chatoyancy exhibits a changeable silky luster as light is reflected within the thin parallel fibrous bands. This effect is due to the fibrous structure of the material. Tiger iron is composed of red jasper and black hematite. The rippled wavy bands of color often resemble a scenic view.
