The appearance or quality of light reflected from the surface of a mineral is known as luster.
In mineralogy, luster refers to how a mineral surface appears in terms of its capacity to reflect light. The degree of transparency, diaphaneity, and structure of a mineral all affect its luster.
A mineral's ability to reflect light is referred to as luster. The first step in identifying a mineral is to measure it. Always examine a brand-new surface for luster; you might need to remove a tiny amount of material to reveal a clean sample. Metallic luster, which is extremely reflective and opaque, to dull luster (non-reflective and opaque.)
Mineralogists use the physical characteristic of luster to identify minerals. A mineral's luster defines how its exterior reflects light and how its inside may bend or refract light. Some minerals have a metallic sheen, while others don't.
A mineral reflects light by having a luster. The two main categories of luster are described by the labels metallic and nonmetallic. The most popular words for luster are shown in Table 7, along with an illustration of a comparable mineral. Some minerals are described as "earthy," "chalky," or "dull" because they lack luster.
