Physical properties
Hardness 2.5 to 3 on the Mohs scale, metallic yellow color, bright metallic luster, cubic crystal system, no cleavage, and very high specific gravity around 19.3.
Formation & geological history
Formed through hydrothermal precipitation in quartz veins, typically deposited by mineral-rich fluids associated with igneous intrusions over millions of years.
Uses & applications
Used primarily in fine jewelry, monetary reserves, electronics manufacturing, and investment-grade specimen collecting.
Geological facts
Gold is extremely malleable and ductile; a single ounce can be drawn into a wire 50 miles long. It does not tarnish or corrode over time.
Field identification & locations
Identify by its high density, softness, yellow color, and lack of reactivity with acids. Commonly panned from alluvial placers and streams globally.
