Corresponding Astrological Sign: Capricorn. Tiger Eye is the Planetary stone for Gemini (May 21-Jun. 20) and the accepted gem for the ninth wedding anniversary.
Tiger Eye 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 Eye is mined in Western Australia, South Africa, USA, Canada, India, Namibia, and Burma.
Variations: "Tiger Iron" is composed of Tiger Eye, red jasper and black hematite. The rippled wavy bands of color often resemble a scenic view. Marra Mamba is a form of tiger iron found in one area of Australia near Mount Brockman. It is a very rare type of tiger iron that contains shades of red, green, yellow, and blue. This area has been mined out for many years so very little of the "true" marra mamba is available today. Because the minerals in this stone are of varying hardness, it is difficult to polish without under cutting.
