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 tiger's eye, red jasper and black hematite. The rippled wavy bands of color often resemble a scenic view. A very rare type of tiger iron contains shades of red, green, yellow, and blue.


Some have a greenish cast with shades of brown, golden yellow, red and blue veining. Because the minerals in this stone are of varying hardness, it is difficult to polish without under cutting

Many legends about quartz say that wearing tiger's eye (which is a form of quartz) is beneficial for health and spiritual well being. Legend also says it is a psychic protector, great for business, and an aid to achieving clarity.
