Luster. Luster is a term used to describe or denote the peculiar 

 character of light reflected from the surfaces of minerals. The differ- 

 ence in quality of reflected light is caused not only by the character 

 of the surface, but also by the structure and index of refraction of the 

 specimen. All faces of the same crystal form, as the cube faces or 

 cubical cleavage surfaces of galena, will have the same luster, while 

 the three pinacoids are at right angles to each other, as the three 

 directions of the cubical cleavage, but each of the pinacoids may 

 have a distinguishing luster.
