The gemstone known as tiger's eye is a form of chalcedony quartz. But it didn't start out as quartz. It began as the fibrous blue mineral called crocidolite, which is made up of iron and sodium. Crociodolite is also known as asbestos. The crocidolite was gradually transformed into quartz while maintaining its fibrous formations.

Tiger's eye is what is known in mineralogy as a pseudomorph. The term comes from the Greek for "false form." Pseudomorphs form when one mineral replaces another. The transformation begins when quartz becomes embedded between the fibers of crocidolite. This process can result in two different gemstones: a blue stone called hawk's eye or the golden brown stone called tiger's eye.

In the course of the process, the crocidolite is completely dissolved. But the quartz takes on the fibrous formations and this creates the parallel lines within the gem which gives it that shifting play of light. Though the iron and sodium of the crocidolite dissolve, traces of the iron oxide remain and this creates the golden color typical of tiger's eye. If less iron is present the quartz will tend towards the blue color of the original crocidolite.

Chatoyant in a broad sense is ?A polished surface ... when turned towards the light often shows a series of lustrous bands alternating with bands of duller color which show little silky luster. The beauty of the effect is enhanced by the fact that the fibers are not always perfectly straight; they may be curved and often have a sharp bend or twist at a certain place. A change in the incident light results in a reversal of the conditions, the dark bands becoming lustrous and the lustrous bands becoming dark. Many are attracted to a magnet because they commonly include bands (i.e., zones), which are typically thin and discontinuous, of magnetite.


Origin Of The Name

Tiger eye with its bands resembles an eye of tiger, so it is received its name due to this similarity. Tiger's eye was first discovered in South Africa in the early 1800's. The first theories about tiger's eye formation were developed in 1873 by the German mineralogist Wilbel in 1873. More recently, a new theory of tiger's eye has been proposed that argues that it is not in fact pseudomorphic, but rather forms from crocidolite by a different mechanism, through a series of cracking and sealing episodes.



Interesting Facts

Tigers eye comes in 3 different colors. Red Tigers Eye, Blue Tigers Eye and Yellow Tigers Eye.

Tiger Eye is the anniversary gemstone for the 9th year of marriage.

Roman soldiers wore tiger's-eye for protection in battle. Tiger Eye was thought to be all seeing due to its appearance.

Soon after Tiger Eye's discovery in the late 19th century. Idar-Oberstein lapidaries discovered they could bleach tiger-eye to an evenly colored light yellow. By using either hydrochloric or oxalic acid. When properly oriented and cut, this material could yield a sharp cat's-eye stone.



Where Is It Found

The most important source of tiger's-eye is South Africa. Commercial quantities have also been recovered from India; Myanmar (formerly Burma); Sri Lanka (formerly Ceylon); the Hamersley range of the Pilbara region and Mt. Brockman, West Australia; Brazil; and California. Pietersite, as mentioned, comes from Namibia (formerly South-West Africa), and from Nangang, Hunan Province, China.



What Do We Do With It

Tigers eye is usually as cabochons, but also as small spheres, diverse prisms (some with rounded edges), faceted forms, small carvings (scarabs, cameos, intaglios, etc.), and even tumbled chips. They also have been carved and fashioned into articles such as boxes, cane heads, eggs, hearts, obelisks, pyramids, snuff bottles, spheres and diverse figures. In addition, especially in the past, they were also used as eyes -- i.e., set into the eye sockets -- of carvings fashioned from other gemrocks, shell and wood.
