About Albite
Albite is the sodium-rich end member of the plagioclase feldspar series, typically appearing white to colorless with a pearly, vitreous luster on cleavage faces. It is one of the most abundant minerals in Earth's crust, found in granites, pegmatites, and metamorphic rocks worldwide. Gem-quality albite is occasionally faceted or used as a matrix for other minerals, and some varieties—such as peristerite—display a beautiful bluish sheen called adularescence.
