Lustre is the way light reflects off the surface of a mineral, and the degree to which it penetrates into the interior. The key distinction is between metallic and non-metallic lustre. Light does not pass through metals, and that is the main reason they look "metallic" (e.g., specular hematite in Figure 2.3.1 and pyrite in Figure 2.3.4b).

A mineral's streak is the color it has when ground to a powder. Some minerals that occur in a range of colors always have the same streak. As a result, streak is considered a more stable indicator than the color of the solid rock. While most minerals have a white streak, a few well-known minerals can be identified by the color of their …

Hematite, on the other hand, is an example of a mineral for which color is not diagnostic. In some forms hematite is deep dull red, but in others it is black and shiny metallic (Figure (PageIndex{2})). Many other minerals can have a wide range of colors (e.g., quartz, feldspar, amphibole, fluorite, and calcite).

Quartz sand is a non-metallic mineral, which is produced during the processing of quartz stone. The main component of quartz sand is SiO2 (90 %–99 %), and its density is 2.65 g/cm 3. Quartz sand has been widely studied for the removal of pollutants in constructed wetlands.
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. Different types of non-metallic luster are described in Table below.
