Physical properties

Hardness: 2.5-3.0 (Mohs scale), Color: Golden yellow, Luster: Metallic, Crystal Structure: Isometric (cubic), Cleavage: None, Specific Gravity: 19.3

Formation & geological history

Formed in hydrothermal veins associated with igneous intrusions; often concentrated in placer deposits (riverbeds) through erosion and water transportation over millions of years.

Uses & applications

Currency, jewelry, electronics (conductive material), aesthetic dental crowns, and investment asset (bullion).

Geological facts

Gold is incredibly malleable; a single ounce can be beaten into a sheet covering 100 square feet. It is one of the few elements found in its 'native' or pure metallic state in nature.

Field identification & locations

Identify by its high density/weight (it will feel 'heavy' for its size), high malleability (it will dent, not shatter when struck), and its golden streak. Found in quartz veins or panning in mountain streams.
