Physical properties

Hardness: 2.5-3.0 Mohs; Color: Metallic yellow/Golden; Luster: Bright metallic; Crystal Structure: Isometric (cubic); Cleavage: None; Specific Gravity: 19.3 (very heavy)

Formation & geological history

Formed in hydrothermal quartz veins via cooling fluids or concentrated in alluvial deposits (placer deposits) through erosion and water transport. Often associated with volcanic activity and metamorphic belts.

Uses & applications

Currency, investment bullion, jewelry making, electronics (conductors), and high-end mineral collection.

Geological facts

Gold is incredibly ductile; a single ounce can be stretched into a wire 50 miles long. Unlike many other minerals, it is chemically inert and does not tarnish or rust.

Field identification & locations

Identify in the field by its high density (weight for size), malleability (it will dent rather than shatter under pressure), and consistent color in shade versus light. Found in stream beds or mountainous quartz outcroppings.
