Tigereye (aka Tiger Eye or Tiger's Eye) is a semi precious gemstone quartz usually with rich yellow and brown stripes, but it can be red or blue.
When blue it carries the trade name Hawk's Eye.
Tigereye is mined primarily in Northern Cape Province, South Africa and Western Australia.
Tigereye contains oriented fibers of crocidolite that have been replaced by silica. The fibers are twisted or crumpled instead of straight, causing a play of light or chatoyancy when you move the stone around. Tigereye is a metamorphic rock and gets it color from iron oxide.
Tiger Eye gemstone cabochons are vitreous (hard, unbendable and glasslike) and they are a member of the Chalcedony family.
With its strong chatoyance, the semi precious stones get their name from its resemblance to the eye of a tiger. These gorgeous jewelry cabochons seem to glow with an inner light.
When cutting and polishing Tiger's Eye cabochons, skillful orientation to the fibrous structure must be applied to achieve the best chatoyancy. Ideally the cut should be perfectly parallel to the length of the fibers to achieve fullest chatoyancy.
Tiger's Eye cabochons have a hardness of 7 and take a great polish.
