Physical properties
Hardness: 2.5-3.0 Mohs; Color: Metallic yellow; Luster: Metallic; Crystal Structure: Isometric; Cleavage: None; Specific Gravity: 19.3
Formation & geological history
Formed primarily in hydrothermal quartz veins or as secondary deposits (placer deposits) through weathering; found in igneous and metamorphic rocks across many geological ages.
Uses & applications
Extensively used in jewelry, electronics, dentistry, and as a financial investment/standard.
Geological facts
Gold is extremely ductile; one ounce can be stretched into a wire 50 miles long. It is chemically inert and does not tarnish.
Field identification & locations
Identified by its high density (heaviness), bright yellow streak, and extreme malleability. Commonly found in quartz veins or stream beds.
