How can color and Luster be used to identify a mineral?
Luster describes the way a mineral reflects light. Measuring it is the first step in mineral identification. Always check for luster on a fresh surface; you may need to chip off a small portion to expose a clean sample. Luster ranges from metallic (highly reflective and opaque) to dull (nonreflective and opaque).
What determines color of a mineral sample?
Color in minerals is caused by the absorption, or lack of absorption, of various wavelengths of light. The color of light is determined by its wavelength. When pure white light (containing all wavelengths of visible light) enters a crystal, some of the wavelengths might be absorbed while other wavelengths may be emitted.
