3 Mineral Properties - Mineralogy - OpenGeology

These four properties (luster, color, diaphaneity, and shape) are basic for mineral identification. Other properties including streak (the color of a mineral when powdered), the way a mineral breaks (cleavage, parting, fracture), and hardness are also common keys to identification. Still, other properties can be important for specific minerals.
