Gold Nugget

Physical Properties

Hardness: 2.5-3 (Mohs scale), Color: Golden-yellow, Luster: Metallic, Structure: Isometric, Cleavage: None, Specific Gravity: 19.3

Formation & Geological History

Formed in hydrothermal quartz veins via high-temperature fluids or concentrated in alluvial placer deposits through erosion and water transport.

Uses & Applications

Used in metallurgy, electronics, dentistry, investment bullion, and high-end jewelry.

Geological Facts

Gold is incredibly ductile; a single ounce can be drawn into a wire 50 miles long. Most nuggets are found in streams where heavy gold settles in the slower-moving water.

Field Identification & Locations

Identify by its high density (heavy for its size), malleability (it dents rather than shatters), and lack of a streak (it leaves a golden-yellow streak). Commonly found in riverbeds and mountainous terrain.
