Cymophane or chrysoberyl cat's eye, belongs to the family of chrysoberyl, which is a cluster of rare oxide minerals. The name chrysoberyl comes from a combination of two Greek words, namely "chrysos" - gold and "beryllos" - beryllium.

Cymophane may be called cymophanitis. Its name also comes from the Greek language in conjunction with the words "kyma" - wave and "fainio" - to show.

Cymophane can have many variations in the saturation of yellow with shades of green and gray. Rarely found in blue. It has a vitreous, oily shine, and its Mohs hardness is 8.5 - an important indicator that proves that the stone belongs to the category of noble minerals. In contrast to alexandrite, the purity of which is very high, Cymophane includes many elements, making it opaque.

Cymophane is an extremely valuable and expensive stone because of its rarity. Used to decorate exclusive jewelry . The largest crystal found was 475 carat. The price depends on several factors: the intensity of the effect of the cat's eye, direct and expressive lines, depth of color and transparency.
