Luster: The light-reflecting qualities of a mineral. - Geology

Most mineral specimens do not exhibit a metallic or submetallic luster. These specimens are said to have a "nonmetallic" luster. There are many varieties of nonmetallic lusters, and the most common are described below. Note: The name "nonmetallic" applies to the luster of these minerals and has nothing to do with their elemental composition.
