The gemstone was formed hundreds of millions of years ago during a volcanic era when the Hamersley Ranges were being formed, by highly mineralized silica impregnating the Crocidolite fibers.  The Tiger Eye is enclosed in a jasper host rock through which a banding of Hematite occurs together with splashes of Pyrite.
