There are actually quite a few properties to classify rocks and minerals. Some of these are chemical composition, radioactivity, phosphorescence, grain size, hardness, color, streak and fluorescence.
The term for how a mineral reflects light from its surface is luster. Luster describes the way light interacts with the surface of a mineral, with common types including metallic, vitreous (glassy), pearly, and silky.
The physical property used to describe how the surface of a mineral reflects light is called luster. Luster describes how light interacts with the surface of a mineral, with terms like metallic, vitreous (glassy), pearly, or dull being commonly used to characterize different types of luster.
Cleavage is the tendency of a mineral to break along flat planar surfaces as determined by the structure of its crystal lattice. Fracture is the way a mineral breaks other than along a cleavage plane. They both describe a way a mineral can break.

Breakage in minerals refers to how a mineral breaks when subjected to external forces such as impact or pressure. It is used to describe the way a mineral fractures or cleaves along certain planes or directions, which can help identify the mineral based on its unique breakage pattern.
The word used to describe a mineral if no light passes through it is "opaque." This means that the mineral is not transparent or translucent, and light cannot penetrate through it.

The term used to describe how light is reflected from a mineral surface is "luster." Luster refers to the appearance of the mineral's surface when light interacts with it, and it can be described as metallic, vitreous (glassy), pearly, silky, or dull, among others.
The words waxy, pearly, and dull describe a mineral's luster.
