What is Tiger's Eye?
Tiger's Eye is a chatoyant gemstone, typically a metamorphic rock with a golden to reddish-brown color and a silky luster. This effect is caused by the parallel intergrowth of quartz crystals and altered crocidolite fibers. The stone exhibits a distinctive 'eye' effect, a shimmering band of light that moves as the stone is turned. It is often used in jewelry and is believed by some to have metaphysical properties.
