About
Albite
Albite is a sodium-rich aluminum silicate mineral from the plagioclase feldspar group and is a major component of the Earth’s continental crust. It commonly forms in igneous rocks like granite and pegmatites, as well as in metamorphic and hydrothermal environments. Albite is usually white or colorless but may show soft shades of blue, gray, or green due to impurities. A key identifying feature is its fine parallel striations on crystal surfaces. It has a vitreous to pearly luster, giving it a subtle and elegant look. Transparent varieties can be cut into gemstones, though it is mostly valued by collectors. A special variety called Peristerite shows a soft blue iridescent sheen. Overall, Albite is appreciated for its geological importance, gentle beauty, and calming energy.
