Physical properties

Hardness: 2.5-3 on Mohs scale; Color: Silver-white (tarnishes to black/grey); Luster: Metallic; Crystal Structure: Isometric (Cubic); Cleavage: None; Specific Gravity: 10.5

Formation & geological history

Formed in hydrothermal veins and through the oxidation of silver-bearing deposits. Often associated with volcanic activity and high-heat geological environments.

Uses & applications

Primary use in jewelry, investment (bullion), electronics, solar panels, photography, and industrial catalysts.

Geological facts

Silver is the most reflective element on the periodic table and has the highest electrical and thermal conductivity of any metal.

Field identification & locations

Identify by Hallmark stamps (925 for Sterling), high density, and the 'ice test' (silver conducts heat so well it melts ice instantly). Commonly mined in Peru, Mexico, China, and Chile.
