Tiger's eye forms through a process called pseudomorphism, which involves the replacement of one mineral by another while retaining the original mineral's shape. The process begins with a rock rich in crocidolite, a type of asbestos composed of fibrous crystals of the mineral riebeckite. Over time, geological processes introduce silica-rich fluids into the rock where crocidolite is present. These silica-rich fluids slowly infiltrate the rock, depositing quartz (silicon dioxide, SiO2) in place of the crocidolite fibers. As the quartz infiltrates the crocidolite-rich rock, it replaces the original mineral while preserving the fibrous structure of the crocidolite. This new quartz formation maintains the fibrous structure and parallel alignment of the crocidolite fibers, creating the unique chatoyant effect observed in tiger's eye. When light interacts with these fibers, it reflects off them, producing a luminous band of light that moves across the surface of the stone when it is rotated or tilted.\u003c\/p\u003e\n\u003cp class=\"p1\" data-mce-fragment=\"1\"\u003eThe red color of these tumbles comes from heating regular golden tigers eye to high temperatures, which causes it to turn a bright red color.
