There are several varieties of cat's eye stones, which are distinguished by their distinct optical phenomenon known as chatoyancy. Types of Cat's Eye Stone include chrysoberyl cat's eye, which is the most popular; it is valued for its bright, pointed band. A variety of colors can be seen in cat's eye tourmaline, another noteworthy variety, and cat's eye quartz, which has a softer sheen. Less frequently found cat's eye apatite and cat's eye scapolite also have an eye-like appearance. Because each variety differs in color, hardness, and clarity, it makes them desirable for various jewelry pieces and collections. Cat's eye stones are enticing because of their enigmatic, shifting light.
