Physical properties
Mohs hardness of 2.5-3; bright yellow color with metallic luster; cubic crystal system rarely seen as well-formed crystals; specific gravity is extremely high at 19.3.
Formation & geological history
Forms through hydrothermal fluids circulating in quartz veins or through supergene enrichment in placer deposits over millions of years.
Uses & applications
Used primarily in jewelry, investment bullion, electronics manufacturing, and dentistry.
Geological facts
Gold is so malleable that a single ounce can be beaten into a sheet covering 300 square feet. The largest nugget ever found was the Welcome Stranger in Australia, weighing over 2,300 ounces.
Field identification & locations
Identified by its high density, distinct yellow color that does not tarnish, and malleability rather than brittleness. Found in alluvial stream beds and lode deposits worldwide.
