Note cubic structure and silver-gray colour. Another view of galena's cubic crystalline habit Underside of specimen in previous photos Mineral Picture courtesy of www.yuprocks.com GalenaPbS Class: Sulfide Hardness: 2.5 Density: 7.6 Streak: Lead gray Lustre: Metallic Habit: Excellent cubic cleavage, crystals usually very evident Colours: Lead gray    Crystal System: Isometric Cleavage: Perfect cubic Fracture: Subconchoidal Magnetism: None Reaction with HCl: Weak Identification in hand sample: Gives off a rotten-egg smell in HCl, very high SG, very metallic lustre. Associations: Very common in hydrothermal sulfide deposits. Associated with sphalerite, pyrite, chalcopyrite, quartz, calcite, fluorite, and/or barite. Industrial / ecomonic uses: Main ore from which lead is extracted, also a source of silver.    Inaccurate data? Better photos? .
