This material has been lab created, a synthetic gemstone that exhibits a luminous band that resembles a cat's eye. The quality of displaying this band is known as chatoyancy. 
 
A method for making synthetic quartz cat's-eye involves drawing a rod from molten quartz with gas bubbles, cutting a transverse section, grinding a convex surface, and polishing. 
 
Cat's eye can also occur naturally in many minerals, including chrysoberyl, green elbaite, pink elbaite, teal-colored elbaite, and white scapolite.
