Gold Nugget

Physical Properties

Hardness: 2.5-3; Color: Golden-yellow; Luster: Metallic; Crystal Structure: Isometric (rarely crystals, usually nuggets/grains); No cleavage; Specific Gravity: 19.3.

Formation & Geological History

Formed in hydrothermal quartz veins by precipitation from hot mineral-rich fluids or weathered out into alluvial placer deposits. Gold is an elemental metal found in various geological ages.

Uses & Applications

Standard for monetary systems, high-end jewelry, electronics (due to conductivity and corrosion resistance), and medicine.

Geological Facts

Gold is chemically inert and does not tarnish. It is so malleable that a single ounce can be beaten into a sheet covering 100 square feet.

Field Identification & Locations

Identify by its high density (feels very heavy for its size), metallic luster that doesn't change when shadowed, and malleability (it will dent rather than shatter). Often found in riverbeds or pan concentrates.
