Physical properties
Hardness of 2.5-3 on the Mohs scale, bright yellow color, metallic luster, cubic crystal system, no cleavage, and very high specific gravity.
Formation & geological history
Formed through hydrothermal processes where gold-bearing fluids precipitate within quartz veins or placer deposits over millions of years.
Uses & applications
Used primarily in jewelry, investment bullion, electronics, and dentistry.
Geological facts
Gold is extremely malleable and ductile; a single gram can be drawn into a wire one kilometer long.
Field identification & locations
Identified by its high density, yellow metallic color that does not tarnish, and softness. Commonly found in alluvial riverbeds and quartz-rich geological formations.
