Mineral Co Feldspar

Feldspars are generally light-colored, including white, pink, tan, green, or gray. The color varies due to impurities within the crystal structure. Feldspar is the mineral that gives granite its pink, green or gray color. When feldspar weathers from igneous or metamorphic rocks, it can accumulate as sand.
