Tiger Eye is a very popular gemstone that displays a chatoyancy (cat's-eye) when a polished stone is moved back and forth in the light. It is a quartz gemstone, usually amber to brown in color, that forms when fibers of the mineral crocidolite are replaced by silica. This structure of parallel fibers is preserved in the stone, and the chatoyant "eye" crosses the parallel fibers at right angles.
