What is Tiger's-Eye?

Tiger's-eye, also called "tiger eye" and "tigers eye," is a very popular gemstone that displays a chatoyancy (cat's-eye) when a polished stone is moved back and forth in incident light. It is a quartz gemstone, usually amber to brown in color, that forms when fibers of the mineral crocidolite are replaced by silica. This structure of parallel fibers is preserved in the stone, and the chatoyant "eye" crosses the parallel fibers at right angles. The best specimens of tiger's-eye are usually cut en cabochon in an orientation that yields the best display of chatoyancy.

A word about spelling...

An internet search will show that not everyone agrees on how to spell the name of this gemstone. Many people are unclear if it should be "tiger" or "tigers" or "tiger's" in addition to whether or not a hyphen is used.

For this article, we have come to the conclusion that "tiger's-eye" is the most proper way for the name to be written. That is how it is written in Gemstones of the World by Walter Schumann, which is an authoritative book with the distinction of having more copies in print than any other book about gems. The stone also appears as "tiger's-eye" in GIA course materials.

Of course, other variations are not necessarily incorrect; however, we believe that since "tiger's-eye" seems to be preferred by some gemologists, scholars, and punctilious editors, then that is also how it should appear on Geology.com.

Tumbled Tiger's-Eye

Tiger's-eye is frequently used as a rough in the production of tumbled stones. It has a hardness of 7 and tumbles well with other quartz gemstones and with agates or jaspers. It easily takes a high polish in a rock tumbler and is suitable for beginning to experienced tumblers.
