Physical properties
Hardness: 2.5-3 (Mohs). Color: Silver-white on fresh surface, tarnishing to gray/black. Luster: Metallic. Crystal Structure: Isometric/Cubic. Specific Gravity: 10.1-11.1.
Formation & geological history
Formed as a primary mineral in hydrothermal veins, often associated with lead, zinc, and copper deposits. Can also form as a secondary mineral in oxidation zones of ore deposits.
Uses & applications
Highly valued for coinage, investment bullion, electronics (excellent conductor), jewelry, and as a collectible geological specimen.
Geological facts
Silver is the most reflective element and has the highest thermal and electrical conductivity of all metals. Most silver is produced as a byproduct of mining other metals like copper and gold.
Field identification & locations
Identify by high density, malleability (it can be flattened with a hammer), and metallic silver luster. Specimens often show dendritic (branch-like) or wire-like growth patterns.
