Physical properties
Mohs hardness of 2.5-3; yellow color with a metallic luster; isometric crystal system; exceptionally high specific gravity around 19.3.
Formation & geological history
Formed through hydrothermal processes where gold-bearing fluids precipitate within quartz veins, later liberated via weathering and placer concentration.
Uses & applications
Used primarily in jewelry, monetary reserves, investment bullion, and specialized electronics due to high conductivity and corrosion resistance.
Geological facts
Gold is extremely malleable; a single ounce can be beaten into a sheet covering 300 square feet. The largest nugget ever found was the Welcome Stranger in Australia.
Field identification & locations
Identify by its high heft, yellow color that does not tarnish, and malleability rather than brittleness. Found in alluvial placer deposits worldwide.
