Physical properties

Hardness: 2.5-3.0 on Mohs scale; Color: Golden-yellow; Luster: Metallic; Crystal Structure: Isometric (cubic); Cleavage: None; Specific Gravity: 15.5-19.3

Formation & geological history

Formed through hydrothermal processes where hot, mineral-rich fluids circulate through crustal fractures. Often found in quartz veins or as secondary 'placer' deposits in riverbeds. These specimens can range in age from millions to billions of years depending on the host rock formation.

Uses & applications

Primary source for investment gold, high-end jewelry, electronics (due to conductivity), and as highly sought-after geological specimens for collectors.

Geological facts

Gold is one of the most malleable metals; a single grain can be beaten into a sheet covering several square feet. Most 'nuggets' found in streams are around 70-95% pure gold, with the remainder usually being silver or copper.

Field identification & locations

Identify by its high density (feels heavy for its size), extreme malleability (it will dent, not shatter, when struck), and its golden streak. Common in areas with historical volcanic activity or mountainous streambeds.
