Chrysoberyl Cat’s Eye show fine parallel inclusions produce a silver white line, which appears as moving light-ray in a cabochon cut stone.The name Chrysoberyl cats eye derived from this effect, which reminds one of the pupil of a cat.The short term “cats-eye” always refers to Chrysoberyl; all other cats-eye must be designated by an additional name.

Chrysoberyl is a beautiful gem and well suited for jewellery use. The combination of high hardness (8.5) and indistinct cleavage make it very durable. Although its dispersion is low, it is a very bright and colourful gem. Cats eye Chrysoberyl is also available. Other gems such as diopside and apatite may be called cats eyes, but Chrysoberyl was the original cats eye gem. It is the finest cat eye of gems. The silky fibers are so fine that a microscope is needed to see the individual fibers. This creates a very sharp cats eye effect.

It can change from shades of green or blue-green in daylight to shades of mauve, violet, purple or even red in incandescent light. Alexandrite is also available as a cats eye gem.
