3 Mineral Properties – Mineralogy
In the case of luster, we usually start by dividing minerals into those that are metallic and those that are nonmetallic. The pyrite seen above is metallic. The quartz is nonmetallic. There are, however, many metallic and many nonmetallic minerals; other properties must be considered if minerals are to be identified correctly.

3.2 How to Identify Minerals
One straightforward 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, but there are still a variety of ways to describe how the light reflects off the mineral. Let's take a look below:
