Detailed explanation-1: -Luster is how a mineral reflects light. The terms metallic and nonmetallic describe the basic types of luster.

Detailed explanation-2: -Luster is how the surface of a mineral reflects light. It is not the same thing as color, so it is crucial to distinguish luster from color. For example, a mineral described as “shiny yellow” is being described in terms of luster (“shiny”) and color (“yellow”), which are two different physical properties.

Detailed explanation-3: -Answer and Explanation: Luster is the property that describes the way a material reflects light.

Detailed explanation-4: -lustre, in mineralogy, the appearance of a mineral surface in terms of its light-reflective qualities. Lustre depends upon a mineral’s refractive power, diaphaneity (degree of transparency), and structure.

Detailed explanation-5: -The luster of a mineral describes the way a mineral reflects light from its surface. Some minerals reflect light the way highly polished metal does. This is called metallic luster. Some minerals that do not reflect light appear dull.
