Physical properties
Hardness: 2.5–3.0 on Mohs scale; Color: Silver-white, often tarnishing to black/gray; Luster: Metallic; Crystal Structure: Isometric (cubic); Cleavage: None; Specific Gravity: 10.5
Formation & geological history
Found in hydrothermal veins and oxidation zones of silver-bearing ore deposits. Formed via hydrothermal precipitation or through secondary enrichment processes in sedimentary or metamorphic host rocks.
Uses & applications
Primarily used in jewelry, coinage, electronics (due to high conductivity), photography, and as a valuable investment or collector's specimen.
Geological facts
Silver is the most reflective element and has the highest electrical conductivity of any metal. Native silver occurs in nature as wires, branched dendrites, or nuggets like this specimen.
Field identification & locations
Identify in the field by its high density (feels heavy for its size), malleability (it will bend rather than break), and metallic luster. Common locations include Mexico, Peru, Canada (Ontario), and the USA (Arizona/Nevada).
