Physical properties

Hardness: 2.5–3 on Mohs scale; Color: Golden yellow; Luster: Metallic; Crystal Structure: Isometric/Cubic; Cleavage: None; Specific Gravity: 19.3 (very high density).

Formation & geological history

Formed primarily in hydrothermal quartz veins or as placer deposits in sedimentary environments; often associated with volcanic activity and tectonic plate boundaries.

Uses & applications

Used extensively in jewelry, electronics (due to high conductivity), medicine, and as a financial standard or investment.

Geological facts

Gold is incredibly ductile; a single ounce can be drawn into a wire 50 miles long. It is also chemically inert, meaning it does not rust or tarnish.

Field identification & locations

Identify by its high density, metallic luster, and sectility (can be cut with a knife). Commonly found in the Witwatersrand basin (South Africa), Nevada, and Western Australia.
