2.1" Albite Crystals with Chlorite Inclusions - Pakistan
This is a 2.1" wide albite crystal formation that contains green chlorite inclusions, collected from Shigar Valley in Pakistan. Small epidote crystals can be found along the base of the albite crystals, along with an unidentified white fibrous mineral. Due to the asbestos-like nature of the fibrous mineral, it's suggested that this specimen not be held near the mouth.
Albite is a plagioclase feldspar mineral with the chemical composition Na(AlSi3O8) when in its pure form. It is a major component of granite and granitic pegmatites, and is often found to form in association with quartz, orthoclase, muscovite, hornblende and biotite. In most cases the crystals will be white to colorless, although it has been known to display red, green and blue hues depending on impurities present during formation. Albite earned its name from the Latin word "albus", meaning white (most commonly found color).
