Tiger Eye is a gold-brown, opaque gemstone variety of fibrous quartz. More
specifically, it is a variety of macrocrystalline quartz. However,
unlike most quartz gemstones, tiger's eye is actually a 'pseudomorph' of
quartz. A 'pseudomorph' is what geologists refer to as any mineral that
transforms into another mineral. In the case of tiger's eye, it began
as crocidolite, but was later transformed into quartz. Crocidolite is
one of the several forms of asbestos. It is a fibrous blue mineral and
belongs to the riebeckite family of amphibole silicates. The
transformation of tiger's eye begins when quartz slowly becomes embedded
between the fibers of crocidolite, eventually the quartz completely
replaces crocidolite while still retaining the original fibrous shape.
