Physical properties

Hardness: 2.5-3.0 Mohs; Color: Rich golden yellow; Luster: Metallic; Crystal Structure: Isometric; Cleavage: None; Specific Gravity: 19.3

Formation & geological history

Formed in hydrothermal quartz veins or as placer deposits in riverbeds where erosion has concentrated the heavy metal. Often associated with volcanic activity or mountain-building events.

Uses & applications

Used in investment/bullion, jewelry making, electronics due to high conductivity, and specialized medical/astronautical equipment.

Geological facts

Gold is incredibly ductile; a single ounce can be stretched into a wire five miles long. It is also one of the few elements found in its 'native' or pure form in nature.

Field identification & locations

Identify by its high density (feels heavy for its size), extreme malleability (it will dent rather than shatter if struck), and the fact that its color remains consistent in different lightings.
