Physical properties

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

Formation & geological history

Formed through hydrothermal activity in veins or as a secondary byproduct in the oxidation zones of ore deposits. Native silver has been mined for thousands of years, with major deposits dating from various geological eras.

Uses & applications

Primary use in jewelry (often as Sterling Silver), bullions, coinage, electronics due to high conductivity, and photography (historically).

Geological facts

Silver is the most reflective element and has the highest electrical and thermal conductivity of any metal. The jewelry shown is a 'Figaro' style chain, likely made of 925 Sterling Silver.

Field identification & locations

Identify in the field by its high density, extreme malleability, and characteristic metallic luster. Commonly found in Peru, Mexico, China, and the Western United States. Look for '925' or 'Sterling' hallmarks on the clasp.
