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.
