Physical properties
Hardness: 2.5–3 on Mohs scale; Color: Silver-white (leads to black/gray tarnish); Luster: Metallic; Crystal Structure: Isometric (cubic); Cleavage: None; Specific Gravity: 10.5
Formation & geological history
Formed in hydrothermal veins and oxidation zones of silver-bearing ore deposits, typically associated with copper or lead.
Uses & applications
Used in electronics due to high conductivity, jewelry, silverware, photography, and as a precious metal investment.
Geological facts
Silver has the highest electrical conductivity, thermal conductivity, and reflectivity of any metal known to man.
Field identification & locations
Identify by its high density (feels heavy for its size), malleability (it will bend rather than shatter), and metallic luster beneath any superficial tarnish.
