Nonmetallic-glassy luster. Large crystals are elongate and may have 6 facets but are not cleavage planes. Garnet (3) Deep reddish purple. No streak. Hardness = 8. Conchoidal fracture. Nonmetallic-glassy luster. Well-formed crystals are spherical with many facets that are not cleavage planes.

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).

Non-metallic minerals are typically poor conductors of electricity and heat, which influences their utility and role in various applications. Hence, the conductive properties form a distinctive difference between metallic and non ...

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.
