Tiger Eye

Tiger Eye or Chatoyant Quartz as it is also known, there are three varieties of this type of quartz. It is the inclusion of croicidolite (blue asbestos) that causes a cat’s eye effect known as chatoyancy.

Product Description

FOUND IN: SOUTH AFRICA, AUSTRALIA, CANADA, INDIA, NAMIBIA, BURMA & USA

Tiger 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 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.

Tiger Eye will display different colors according the exact nature and amount of the inclusions. Grayish yellow, semi translucent appearance of the cat’s eye is due to inclusions of croicidolite and , less commonly hornblende, it has quite a silky luster. Tiger Eye is black with iron oxide staining that gives the yellow and golden brown stripes. Hawk’s Eye forms when the croicidolite changes to quartz but the blue-gray or blue-green color of the original material remains. Whew!

This quartz composite gemstone begins as a fibrous blue mineral called croicidolite, which is comprised of iron and sodium. The transformation begins as clear quartz becomes imbedded between the fibers of crocidolite, and the completed process will result in one of two gemstones; a blue stone called Hawk’s Eye or the golden brown stone called Tiger’s Eye.

As the gem is created the iron and sodium are completely dissolved, the quartz takes on the fibrous formations as well as the blue color of crocidolite. This creates the parallel lines within the gemstone giving it the liquid luster and light movement the stone is so loved for.

Even though the iron and sodium dissolve, traces of hydrated oxide of iron are left behind between the crocidolite and quartz, creating the yellows that are common to both Hawk’s Eye & Tiger Eye. How much of this mineral is deposited will determine how red, yellow or brown a Tiger Eye will be. The rarer blue Hawk’s Eye will have only the slightest amounts.
