Physical properties

Hardness: 2.5–3.0 on the Mohs scale; Color: Golden yellow to brassy yellow; Luster: Metallic; Crystal Structure: Isometric (cubic); Cleavage: None; Specific Gravity: 19.3 (pure)

Formation & geological history

Formed via hydrothermal veins in igneous environments or concentrated in sedimentary 'placer' deposits through erosion and water transport. Often associated with quartz veins and volcanic activity.

Uses & applications

Primarily used in jewelry for its beauty and malleability, as well as in electronics, dentistry, and aerospace for its high conductivity and resistance to corrosion.

Geological facts

Gold is one of the densest chemical elements. It is so malleable that a single ounce can be beaten into a sheet covering 100 square feet. Historically, it has served as the foundation for global monetary systems.

Field identification & locations

Identified by its high density, metallic luster, and sectility (ability to be cut with a knife). Common locations include Witwatersrand (South Africa), Carlin Trend (Nevada), and various alluvial deposits in California and Australia.
