Physical properties
Mohs hardness 2.5 to 3, metallic golden yellow color and luster, cubic crystal system, highly malleable and ductile with no cleavage, and a high specific gravity of 19.3.
Formation & geological history
Formed through hydrothermal processes where mineral-rich fluids precipitate gold in quartz veins, frequently weathered and deposited in alluvial placer streams.
Uses & applications
Used primarily in fine jewelry, monetary reserves, investment bullion, electronics, and aerospace applications.
Geological facts
Gold is chemically inert, meaning it does not tarnish or corrode over time, and a single ounce can be drawn into a wire 50 miles long.
Field identification & locations
Identified by its high density, softness, and distinct golden luster that does not streak black on unglazed porcelain. Commonly found in river placers worldwide.
