Physical properties

Formation & geological history

Formed typically in hydrothermal veins, often associated with other metal sulfides and native elements, deposited from aqueous solutions at moderate to low temperatures.

Uses & applications

Used primarily in jewelry, silverware, electronics, coins, and industrial applications.

Geological facts

Native silver is relatively rare as most silver is extracted from sulfide ores like argentite and galena. Historically, major discoveries of native silver occurred in places like Kongsberg, Norway and Cobalt, Ontario.

Field identification & locations

Can be identified by its high density (heavy for its size), metallic luster, and characteristic tarnish. Found in hydrothermal vein deposits often associated with volcanic activity.
