Physical properties
Mohs hardness 2.5-3; bright yellow color with metallic luster; isometric crystal system, rarely well-crystallized; high specific gravity around 19.3.
Formation & geological history
Formed through hydrothermal processes in quartz veins, later concentrated in alluvial placer deposits through weathering and erosion over millions of years.
Uses & applications
Primary use is in jewelry, investment bullion, electronics, and dentistry due to its high conductivity and resistance to tarnish.
Geological facts
Gold is extremely malleable and ductile; a single ounce can be drawn into a wire 50 miles long. The largest nugget ever found was the Welcome Stranger in Australia, weighing over 2,300 ounces.
Field identification & locations
Identified by its high weight, yellow metallic color, and resistance to acid and scratching. Found globally in rivers and bedrock mining areas, highly sought after by prospectors.
