Physical properties

Formation & geological history

Forms in hydrothermal veins and through weathering and erosion, which concentrate gold in stream placers. Gold deposits range from ancient to geologically recent; the specimen’s age and source cannot be determined from the image.

Uses & applications

Used in jewelry, coins, electronics, dentistry, and investment; natural nuggets are also collected.

Geological facts

Gold is highly malleable and resists oxidation, helping it persist in sediments and remain bright over time.

Field identification & locations

Recognize gold by its dense feel, persistent yellow color, and malleability; it does not flake like mica or tarnish like many sulfides. Common sources include placer deposits and quartz veins worldwide.
