Physical properties
Hardness: 2.5-3.0; Color: Metallic golden-yellow; Luster: Metallic; Crystal system: Isometric; Cleavage: None; Specific Gravity: 19.3
Formation & geological history
Formed in hydrothermal quartz veins or as placer deposits in riverbeds through erosion and concentration. Found in rocks of various geological ages, often Archean or Proterozoic.
Uses & applications
Used in jewelry, electronics, currency, and as a store of value. Highly sought after by collectors and investors.
Geological facts
Natural gold nuggets are rare; less than 2% of the world's gold is found in nugget form. The 'Welcome Stranger' is the largest alluvial gold nugget ever found.
Field identification & locations
Identify by its high density (feels very heavy for its size), malleability (will dent, not shatter), and brilliant metallic luster that does not tarnish. Found in auriferous regions using gold pans or metal detectors.
