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: -Lustre or sheen describes how light is reflected from a mineral’s surface. It indicates what the mineral surface looks like, disregarding its colour.
Detailed explanation-3: -Physical Impurities Impurities may produce color in minerals. Normally colorless calcite can be colored black by MnO2 or carbon. Tiny specks of red or green minerals can impart their color to minerals. For example, chlorite (green) in quartz, and hematite (red) in feldspar, calcite and jasper.
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: -Naturally Occurring-Minerals are found on Earth and not nan-made. Inorganic-Minerals do not consist of living matter. Solid-Minerals have a definite shape and volume. Crystal Structure-Particles inside minerals form a crystal pattern. More items •26-Jun-2018
