Luster can be subdivided further than those two groups, and narrowing down your mineral's luster can often be very useful for identification. Mineral luster types include: Metallic – Like polished metal, with reflective surfaces; Submetallic – Similar to metallic, but less reflective; Glassy – Translucent or transparent, highly reflective
Luster, also spelled lustre, is a simple word for a complex thing: the way light interacts with the surface of a mineral. This gallery shows the major types of luster, which range from metallic to dull. I might call luster the combination of reflectance (shininess) and transparency.

A mineral's luster depends on factors like its chemical composition, crystal structure, surface irregularities, and the presence of impurities. Luster ranges from the gorgeous flashing brilliance of diamonds to the dull, earthy looks of some clay minerals. The role of luster in mineral identification cannot be understated.
Luster & Transparency. How does a mineral reflect light? Luster is the appearance of a fresh mineral surface when reflecting light. It has nothing to do with the color of the mineral, but the scattering of light off the mineral surface. Here is a visual guide to the different types of mineral lusters! [1]

Luster describes the reflection of light off a mineral's surface. Mineralogists have special terms to describe luster. One simple way to classify luster is based on whether the mineral is metallic or non-metallic. Minerals that are opaque and shiny, such as pyrite, have a metallic luster. Minerals such as quartz have a non-metallic luster.
