| − | '''Luster''' is the surface appearance of a substance, or the manner in which it reflects light. The luster of [[minerals]] varies with the nature of their surfaces. A variation in the quantity of light reflected produces different degrees of [[intensity]] of luster; a variation in the nature of the reflecting surface produces different kinds of luster.
