Tigereye

Tigereye: (also spelled tiger’s-eye or tiger eye) is a semiprecious Quartz gem displaying chatoyancy (a vertical luminescent band). Tigereye typically has alternating yellow or brown bands that roll across the surface and catch the light, resembling the eye of a tiger.. With a Moh’s Scale hardness of 7, its tawny brown color is derived from iron oxides. However, when heated the stone’s color changes from brown to red, thus creating the alternative "Red Tigereye" also sold on the jewelry market today. The most important mine for Tigereye is in South Africa, but it is also mined in Western Australia, USA, Canada, India, Namibia, and Burma. Roman soldiers wore Tigereye for protection in battle because it was thought to be "all seeing" due to its appearance. Physically, it is also said to relieve high blood pressure as well as psoriasis, bronchial asthma, kidney, rheumatic and heart diseases. Tigereye is believed to be useful in focusing the mind and is credited for giving protection during travel. It is thought to strengthen one’s convictions and confidence, thereby being very beneficial for the weak and sick.
