It highlights the reliability of streak over color, defines luster and hardness with Mohs scale, and discusses cleavage types influenced by atomic arrangement. Examples like graphite and calcite illustrate cleavage distinctions.

Color can be unreliable; however, streak offers a consistent identification approach. Luster is categorized as metallic or non-metallic, while hardness is measured using the Mohs Hardness Scale. Additional properties like cleavage, fracture, fluorescence, and magnetism assist in distinguishing minerals.
