Physical properties
Gold: Hardness 2.5-3, golden yellow color, metallic luster, isometric crystal structure, high specific gravity (19.3). Black sand: Mostly heavy iron oxides.
Formation & geological history
Formed in hydrothermal veins and concentrated in placer deposits by water action due to high density.
Uses & applications
High value in electronics, jewelry, coinage, and as an investment asset.
Geological facts
Gold is incredibly malleable; a single ounce can be beaten into a sheet covering 100 square feet.
Field identification & locations
Identify by its distinct yellow metallic luster that does not change with viewing angle, malleability (won't shatter), and high weight compared to black sand.
