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).
