Physical properties
Hardness: 2.5–3.0 on Mohs scale; Color: Golden-yellow; Luster: Metallic; Crystal Structure: Isometric; Cleavage: None; Specific Gravity: 19.3 (very heavy)
Formation & geological history
Formed via hydrothermal fluids in quartz veins or as placer deposits in riverbeds where erosion has concentrated the heavy metal over geological eras.
Uses & applications
Used in jewelry, currency, electronics (due to high conductivity), dentistry, and as a financial investment/store of value.
Geological facts
Gold is chemically inert, meaning it does not rust or tarnish. Almost all gold found on Earth came from meteorite impacts during the planet's early history.
Field identification & locations
Identify by its high density (it will feel much heavier than it looks) and malleability; unlike pyrite, gold will dent or flatten under pressure rather than shattering. Often found in river bends or cracks in bedrock.
