Tiger’s Eye is the best know variety of chatoyant Quartz (or Cat’s Eye
Quartz). Tiger’s Eye, with its bands resembling the eye of a tiger,
received its name due to this similarity. Tiger’s Eye is also called
Crocidolite Cat's Eye or African Cat's Eye. Tiger’s Eye has rich yellow
and golden brown stripes, with a fine golden luster when polished.

Coveted since antiquity, Roman soldiers wore Tiger’s Eye for protection
in battle. Due to its appearance, in the ancient world Tiger’s Eye was
thought to be all seeing, offering protection during travel,
strengthening of convictions and confidence.
Many legends say that wearing Tiger’s Eye is beneficial for health and
spiritual well being. Legend also says it is a psychic protector, great
for business and aids in achieving clarity of mind.
Today, crystal healers use Tiger’s Eye for focusing the mind.

Quartz gemstones are commonly separated into two groups based on the
size of their individual crystals. The macrocrystalline Quartz (large
crystal) group includes many popular gemstones such as Tiger’s Eye,
Amethyst, Ametrine and Citrine. Cryptocrystalline Quartz includes
species whose individual crystals are too small to be easily
distinguished. Apart from being a variety within the group, Chalcedony
is also a catch all term to describe cryptocrystalline Quartz and
includes many gems that have been coveted since antiquity.
Tiger’s Eye is a pseudomorph (the result of one mineral replacing
another) that contains oriented fibers of Crocidolite that have been
replaced by silica.
Tiger’s Eye displays chatoyancy (a vertical luminescent band like that
of a Cat's Eye). Tiger’s Eye typically has lustrous alternating yellow
or brown bands. Cutting is crucial with Tiger’s Eye because the rough
crystals reveal little or nothing of the exciting chatoyancy of the
finished gem.
