Mineral Identification | Earth Science
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.
What are Non-Metallic Minerals?
Non-metallic miner als, also known as non-metals, are a diverse group of elements that do not possess metallic properties. They are soft, brittle, and generally have low melting and boiling points. Non-metallic minerals play a vital role in the environment, economy, and daily life. This article will provide a comprehensive overview of non ...

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).
