Physical properties

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

Formation & geological history

Formed in hydrothermal quartz veins or as secondary deposits in riverbeds (placers) through erosion of mountain ranges. Formation can date back billions of years.

Uses & applications

Highly valued for jewelry, investment bullion, electronics (excellent conductor), and medical applications.

Geological facts

Gold is one of the most ductile and malleable metals; a single ounce can be stretched into a wire 50 miles long. It is chemically inert and does not tarnish.

Field identification & locations

Identified by its high density (weight), metallic luster that doesn't change when shadowed, and extreme malleability (it will dent rather than shatter). Found globally in mining districts and river sediment.
