![]() Tiger's eye is normally golden brown to brownish-gold in color. This results in a more chaotic chatoyancy, rather than the linear chatoyancy of regular hawk's eye and tiger's eye.īuying Tiger's Eye and Determining Tiger's Eye Value Back to Top Tiger's Eye Color Brecciated stones are rocks which are composed of materials that have been broken apart, swirled around, and then later reformed and cemented together by quartz or another type of host or matrix material. Technically, the term pietersite may be used to describe any brecciated tiger's eye or hawk's eye. ![]() During the pseudomorph transformation process, materials that contain more iron oxide result in brownish tiger's eye less oxidation and less iron tends toward the original blue color of crocidolite. Tiger's eye is actually formed from hawk's eye. It is closely related to hawk's eye and pietersite, both of which exhibit similar chatoyancy. Tiger's eye is famed for its remarkable chatoyancy and its attractive golden brown colors. 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. It is a fibrous blue mineral and belongs to the riebeckite family of amphibole silicates. Crocidolite is one of the several forms of asbestos. In the case of tiger's eye, it began as crocidolite, but was later transformed into quartz. A 'pseudomorph' is what geologists refer to as any mineral that transforms into another mineral. However, unlike most quartz gemstones, tiger's eye is actually a 'pseudomorph' of quartz. More specifically, it is a variety of macrocrystalline quartz. Tiger's eye is a gold-brown, opaque gemstone variety of fibrous quartz. ![]() ![]() About Tiger's Eye - History and Introduction ![]()
