Identifying Minerals | Geology

Standard names for luster include metallic, glassy, pearly, silky, greasy, and dull. It is often useful to first determine if a mineral has a metallic luster. A metallic luster means shiny like polished metal. For example cleaned polished pieces of chrome, steel, titanium, copper, and brass all exhibit metallic luster as do many other minerals.

2.6 Mineral Properties | Physical Geology

Other types of non-metallic lustres are "silky," "pearly," and "resinous.". Lustre is a good diagnostic property, since most minerals will always appear either metallic or non-metallic. There are a few exceptions to this (e.g., hematite in Figure 2.16). Hardness. One of the most important diagnostic properties of a mineral …
