Named for its resemblance to the eye color of a magnificent big cat, tiger eye is a kind of chalcedony, which is made of thin layers of multicolored quartz. Tiger’s eye is formed when a type of blue asbestos called crocidolite is replaced by quartz fibers. The asbestos breaks down and leaves a residue of brown iron oxide that gives the tiger eye its color, while the lines of quartz fibers allow for the sought-after lines of light in the jewel. The replacement of crocidolite with quartz also makes tiger eye a pseudomorph, which happens when a mineral gradually replaces another mineral. It’s not surprising that tiger eye is often found in metamorphic rock, which changes from one rock to another over many millennia.
History of Tiger’s Eye
Gemologists believe that tiger eye was worn as early as 2000 years ago by Roman soldiers. The gem was supposed to fortify them before they went into battle. Tiger’s eye was officially “discovered” in the early 19th Century in South Africa, but it took until the latter part of the century for mineralogists to devise a theory as to how it was formed. The theory that the gem is created out of asbestos is still popular, but a newer theory suggests that it is just another form of crocidolite.
Properties of Tiger’s Eye
Tiger’s eye is prized for its chatoyancy, or cat’s eye effect. This looks like a streak of light that seems to hover either just below or just above the surface of the gem. It also has a unique, silky luster.
Tiger’s eye can also form with limonite or hematite to give the gem interesting patterns of red-brown, gray or yellow.
The chemical formula of tiger eye is SiO2, which means it’s made almost entirely of quartz. It has a hardness of 7 on the Mohs hardness scale, which allows it to be tumbled without being damaged. Since it is quartz, it’s also tough enough to be carved fairly easily. Lapidists cut tiger eyes as domed cabochons to highlight the play of light within the gem.
The tiger eye is a type of polycrystalline quartz, which means it features many hexagonal crystals. It has a refractive index of 1.53 to 1.56 and a specific gravity of 2.63 to 2.65. Tiger eye is opaque, which means light does not pass through it. It has an indiscernible cleavage, which means there is no point where it splits neatly. However, some gemologists claim that tiger eye has a very good cleavage. It can fracture when exposing it to sudden changes in heat. Consequently, the red versions of tiger eye are heated gently to improve their appearance.
Though tiger eye is an inexpensive gem, the gem cutter must be quite skillful to cut and polish it in a way that brings out its chatoyancy and its silky luster. It is rarely faceted and has such a singular look that it’s hard to mistake it for any other gemstone.
