Physical properties

Hardness: 2.5-3.0 Mohs; Color: Metallic yellow; Luster: Metallic; Crystal Structure: Isometric/Cubic; Cleavage: None; Specific Gravity: 19.3 (pure)

Formation & geological history

Formed via hydrothermal veins where hot, mineral-rich fluids circulate through fractures in crustal rocks, or within magmatic deposits. Often found in quartz veins or associated with sulfur minerals.

Uses & applications

Primary use is in currency, jewelry, and electronics due to high conductivity and corrosion resistance. Also highly valued by mineral collectors as 'specimen gold'.

Geological facts

About 80% of the world's gold is still buried in the ground. The largest gold nugget ever found was the 'Welcome Stranger', weighing over 70kg.

Field identification & locations

Identify by its soft, malleable nature (it will dent rather than shatter) and high density. Commonly found in areas with past volcanic or tectonic activity.
