Physical properties
Mohs hardness of 2.5 to 3, bright golden-yellow color, metallic luster, cubic crystal system, highly malleable and ductile, with a high specific gravity around 19.3.
Formation & geological history
Formed via hydrothermal vein deposition and in placer deposits, originating from deep Earth geological processes over billions of years.
Uses & applications
Extensively used in jewelry, electronics, investment bullion, and financial reserves due to its scarcity and resistance to corrosion.
Geological facts
Gold is so malleable that a single ounce can be beaten into a sheet covering 300 square feet. It does not tarnish or react with most chemicals.
Field identification & locations
Identified by its distinctive yellow metallic color, high density, and refusal to dissolve in single acids. Commonly panned from riverbeds or mined from lode deposits.
