Lustre (mineralogy)

Lustre or luster is the way light interacts with the surface of a crystal, rock, or mineral. The word traces its origins back to the Latin lux , meaning quot;lightquot;, and generally implies radiance, gloss, or brilliance.

Mineral Luster. Luster is a description of the way a mineral surface looks when light reflects off of the surface. Luster has two categories, metallic and nonmetallic. Metallic Luster refers to minerals that look like a shiny metal. Examples include galena, pyrite, magnetite, and some varieties of hematite.

Luster. A minerals luster is the way it reflects light. Descriptions of luster are very subjective but are sometimes useful. Common types of luster are vitreous (glassy), adamantine (brilliant or gem like), resinous (resin like), greasy, pearly, waxy, and silky.
