Physical properties

Hardness: 2.5–3 on Mohs scale; Color: Silvery-white (tarnishes to black or gray); Luster: Metallic; Crystal system: Isometric (cubic); Cleavage: None; Specific gravity: 10.5

Formation & geological history

Formed in hydrothermal veins and as a byproduct of sulfide mineral oxidation in volcanic and metamorphic environments. Deposits can range from Proterozoic to Cenozoic in age.

Uses & applications

Used extensively in jewelry (as sterling silver), electronics due to high conductivity, photography, mirrors, and investment (bullion).

Geological facts

Silver has the highest electrical and thermal conductivity of any element. Its name comes from the Old English word 'seolfor'. The largest producer of silver in modern times is Mexico.

Field identification & locations

Identify by its high density, metallic luster, and sectility (can be cut with a knife). In the field, look for 'tarnish' and associated minerals like galena or acanthite. Found globally, notably in the Andes Mountains and Southwest USA.
