Cat's-eye info

Any of several gem stones that, when cut en cabochon (in convex kind, highly polished), display a luminous band reminiscent of the attention of a cat; this explicit quality is termed chatoyancy. Treasured, or oriental, cat's-eye, the rarest and most highly prized, is a greenish chatoyant number of chrysoberyl called cymophane; the chatoyant impact is due to minute parallel cavities. Quartz cat's-eye, the most typical, owes its chatoyancy and grayish-green or greenish color to parallel fibres of asbestos in the quartz; though it comes from the East, it is often called occidental cat's-eye to differentiate it from the more helpful oriental (chrysoberyl) cat's-eye. The 2 may be distinguished by their specific gravities; chrysoberyl is much denser. Crocidolite cat's-eye (African cat's-eye), more commonly often known as tigereye (or tiger's-eye), is quartz that comprises oriented fibres of crocidolite which have been changed by silica. Corundum cat's-eye is an imperfect star sapphire or ruby during which the star is reduced to a luminous zone.
