Physical properties

Hardness: 2.5-3 (Mohs scale), Color: silver-white, Luster: metallic, Crystal structure: isometric, Cleavage: none, Specific gravity: 10.1-11.1

Formation & geological history

Formed in hydrothermal veins and oxidation zones of ore deposits. It occurs as a primary mineral or through enrichment processes involving silver-bearing sulfides.

Uses & applications

Used in jewelry, electronics, solar panels, currency, and as a valuable collector's mineral specimen.

Geological facts

Silver was one of the first metals used by humans. It has the highest electrical conductivity, thermal conductivity, and reflectivity of any metal.

Field identification & locations

Identify by its high density (feels heavy for its size), metallic luster, and malleability. Natural nuggets often show a black or dark gray tarnish of silver sulfide (acanthite) when exposed to air.
