Physical properties
Hardness: 2.5-3; Color: Golden yellow; Luster: Metallic; Crystal Structure: Isometric; Cleavage: None; Specific Gravity: 19.3 (pure)
Formation & geological history
Formed in hydrothermal quartz veins by precipitation from hot, mineral-rich fluids deep in the crust. Found as nuggets in alluvial placer deposits through erosion.
Uses & applications
Investment, jewelry, electronics, and aerospace due to its high conductivity and resistance to corrosion.
Geological facts
In the field, gold can be distinguished from 'fool's gold' (pyrite) because it is malleable and can be flattened with a hammer, whereas pyrite will shatter.
Field identification & locations
Identified by its high density and golden streak. Commonly found in stream beds, river gravels, and quartz veins. Essential for collectors in placer mining regions.
