Physical properties
Hardness: 2.5-3; Color: Golden yellow; Luster: Metallic; Crystal Structure: Isometric; Cleavage: None; Specific Gravity: 19.3 (very high)
Formation & geological history
Formed in hydrothermal quartz veins or as secondary alluvial deposits in river beds. Most deposits originated in the Cenozoic or Mesozoic eras.
Uses & applications
Used primarily in jewelry, as currency reserves, in electronics due to high conductivity, and for specimen collecting.
Geological facts
Gold is one of the densest chemical elements. Naturally occurring nuggets are rare and often command a premium price over the spot price of gold bullion.
Field identification & locations
Identify by its high density (heaviness), malleability (it bends rather than breaks), and metallic sheen that does not tarnish. Often found in placer deposits using gold pans.
