Physical properties
Mohs hardness of 2.5 to 3; golden yellow color with metallic luster; crystal structure is isometric (face-centered cubic); no cleavage; very high specific gravity (approx. 19.3).
Formation & geological history
Formed through hydrothermal processes where gold-bearing fluids precipitate out in quartz veins or through weathering and alluvial concentration in placer deposits.
Uses & applications
Used in jewelry, investment bullion, electronics, and dentistry.
Geological facts
Native gold is remarkably malleable and ductile; a single gram can be beaten into a sheet of one square meter.
Field identification & locations
Identified by its distinctive bright yellow color, high density, softness, and resistance to tarnish; commonly found in riverbeds and quartz-rich veins worldwide.
