![]() This top layer is said to have been silicified starting from the surface. This assumption is further supported by the fact that both tiger's eye and hawk's eye occur in the same veins as crocidolite, however in general only at places where these veins appear at the surface. Occasionally hawk's eye shows areas of yellow color, corresponding to tiger's eye, and this is interpreted as an indication that hawk's eye represents an intermediate step in the alteration of crocidolite to quartz and iron oxides. They are completely replaced by quartz and iron oxides in tiger's eye.Īccording to the more common theory, tiger's eye would present a pseudomorph of quartz after crocidolite. The cause of its chatoyance can be embedded fibers of asbestos, as well as actinolite fibers.Īsbestos is a well known useful but hazardous material and can cause lung cancer, but its dangerous fibers are well embedded in hawk's eye and cat's eye and pose no danger for its owner. There is a smaller vein above that is just opening to the right.Ĭat's eye is typically more translucent and brighter, and occurs in a variety of colors, green, yellow, brown, and rarely blue. The fibers run roughly perpendicular to the walls of the vein. This cut and polished specimen from Griquatown, South Africa, shows a little vein of tiger's eye running through the host rock. Due to its fibrous structure, tiger's eye has a somewhat splintery fracture, not unlike wood. The former fibrous structure is preserved in the orientation of the small columnar quartz crystals that grew perpendicular to the walls of the vein. ![]() Though brighter than hawk's eye, tiger's eye is still almost opaque. In tiger's eye the crocidolite fibers appear to have been fully replaced by quartz and the hydrous iron oxide goethite, FeOOH, the latter being responsible for the yellow-brown color. It is usually very dark and almost opaque. Hawk's eye is a partially silicified fibrous blue-gray crocidolite asbestos, so its fibrous structure is due to embedded fibers of crocidolite in quartz. The fine fibrous structure is shown in the close up image of a cut and polished tiger's eye to the right (note the scale). The chatoyance is a result of the fibrous structure of tiger's eye, hawk's eye, and cat's eye. It can also be seen in other minerals, for example in chrysoberyl, which is then named "oriental cat's eye". This effect is named chatoyance because its look resembles an eye of a cat ("chat" is French for cat). Smaller specimen will show only one or two long lines. All "eyes" show a wavy pattern of parallel lines that seem to move when the stone is turned. The most obvious property and the reason for its use as a gemstone is the silky shine that can be seen in polished, and especially in tumbled and cabochon-cut stones.
