The albite base of this cabinet specimen holds hundreds of tiny Microlite crystals. These crystals are generally in excellent condition, but do not exceed 1 mm in length or diameter. Their octahedral form is very good, showing only slight rounding of corners. All have a deep rusty-brown color and a vitreous luster, and are transparent and quite clear. A small amount of muscovite is present.
