Physical properties
Mohs hardness 2.5 to 3, bright yellow color, metallic luster, cubic crystal system rarely seen as distinct crystals, high density and specific gravity around 19.3.
Formation & geological history
Formed through hydrothermal processes where gold-bearing fluids precipitate in quartz veins, subsequently weathered and concentrated in alluvial placer deposits.
Uses & applications
Used primarily in jewelry, financial reserves as bullion, electronics, and sought after by mineral collectors.
Geological facts
Gold is extremely malleable and ductile; a single gram can be beaten into a sheet of one square meter.
Field identification & locations
Identified by its high weight, yellow metallic color that does not tarnish, and lack of reactivity to acids; found worldwide in riverbeds and gold-bearing rock formations.
