'''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.
'''Kinds of Luster''' - The kinds of luster recognized are as follows:
[[Image:Mineral.jpg|right|thumb|200px|Non-metallic minerals of varying luster]]
#[[Metallic]]
#[[Sub-metallic]]
#[[Non-metallic]]
::A. [[Adamantine]]
::B. [[Vitreous luster|Vitreous]]
::C. [[Resinous]]
::D. [[Greasy]]
::E. [[Pearly]]
::F. [[Silky]]
'''Degrees of Luster''' - The ''degrees of intensity'' of luster are classified as follows:
#[[Splendent]]
#[[Shining]]
#[[Glistening]]
#[[Glimmering]]
#[[Dull luster|Dull]]
