Detailed explanation-1: -Most minerals can be characterized and classified by their unique physical properties: hardness, luster, color, streak, specific gravity, cleavage, fracture, and tenacity.
Detailed explanation-2: -Generally, color alone is not the best tool in identification because color can be highly variable. Some minerals can occur in a variety of different colors due to impurities in the chemical makeup of the mineral.
Detailed explanation-3: -Color. Color is rarely very useful for identifying a mineral. Different minerals may be the same color.
Detailed explanation-4: -Minerals are colored because certain wavelengths of incident light are absorbed, and the color we perceive is produced by the remaining wavelengths that were not absorbed. Some minerals are colorless. This means that none of the incident light has been absorbed.
