Physical properties
Mohs hardness 2.5-3; bright yellow color with a metallic luster; isometric crystal system; exceptionally high specific gravity (around 19.3).
Formation & geological history
Formed via hydrothermal vein deposition and later concentrated in alluvial placers through weathering and erosion.
Uses & applications
Used primarily in jewelry, investment bullion, electronics, and dentistry.
Geological facts
Gold is extremely ductile and malleable; a single ounce can be beaten into a sheet covering 300 square feet.
Field identification & locations
Identify by its high heft, yellow metallic color that does not tarnish, and resistance to acid; found in stream beds and quartz veins globally.
