Physical properties

Hardness: 2.5-3.0 Mohs; Color: Metallic yellow to golden-yellow; Luster: Metallic; Crystal Structure: Isometric (cubic); Cleavage: None; Specific Gravity: 15.5-19.3 (very heavy).

Formation & geological history

Formed via hydrothermal veins deep in the Earth's crust or concentrated in alluvial (river) deposits. Gold is an elemental mineral that does not decay or oxidize and can be billions of years old.

Uses & applications

Extremely valuable for currency, jewelry, electronics (due to high conductivity), medicine, and as a hedge against inflation. Highly sought after by collectors for its rare natural form.

Geological facts

Gold is incredibly ductile; a single ounce can be stretched into a wire 50 miles long. Most gold is found in microscopic form; finding a visible nugget in the field is rare.

Field identification & locations

Identify by its high density (feels heavy for its size) and malleability (it bends/dents rather than shattering when hit). It maintains its color even in shade, unlike pyrite which turns dark.
