Physical properties

Hardness: 2.5-3 (Mohs). Color: Golden-yellow. Luster: Metallic. Crystal System: Isometric. Specific Gravity: 19.3. Cleavage: None. Streak: Golden-yellow.

Formation & geological history

Formed primarily in hydrothermal veins and alluvial deposits. Often deposited by cooling hydrothermal fluids inside quartz veins or concentrated in streambeds through erosion as placer deposits.

Uses & applications

Used in jewelry, currency, electronics due to high conductivity, dentistry, and as a stable financial investment. Highly valued by collectors for natural crystalline or nugget form.

Geological facts

Gold is one of the least reactive chemical elements and is solid under standard conditions. Most gold found in nature is alloyed with silver (electrum) or copper. The state of California produces the most gold in the US historically.

Field identification & locations

Identify by its high density (very heavy for its size), metallic luster that does not tarnish, and extreme malleability (it will bend or dent rather than shatter). Found in placer deposits in rivers or lode deposits in quartz.
