However, value aside, one thing is for sure the semi-precious gemstone Lapis Lazuli is as popular today as it was during those times of old! A strong blue, sometimes with a hint of violet, lapis lazuli's value decreases with the presence of white patches (calcite), while small veins of pyrite are often prized. The Egyptians used Lapis for seals, ground it for an eyelid cosmetic and often carved it into vases and figurines.

About Tiger's Eye - History and Introduction.Tiger's 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. Tiger's eye is famed for its remarkable chatoyancy and its attractive golden brown colors. It is closely related to hawk's eye and pietersite, both of which exhibit similar chatoyancy. Tiger's eye is actually formed from 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.
Technically, the term pietersite may be used to describe any brecciated tiger's eye or hawk's eye. 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. This results in a more chaotic chatoyancy, rather than the linear chatoyancy of regular hawk's eye and tiger's eye.
