Physical properties
Hardness: 2.5-3 (Mohs scale), Color: Golden yellow, Luster: Metallic, Crystal Structure: Cubic/Isometric, Specific Gravity: 19.3 (pure)
Formation & geological history
Formed via hydrothermal veins or as alluvial placer deposits in riverbeds where gold eroded from its primary source. Geological age varies from billions of years (Archean) to recent.
Uses & applications
Investment, jewelry, electronics, and souvenir collecting. These specific flakes are likely decorative or souvenir grade.
Geological facts
Gold is one of the most ductile and malleable metals; one ounce can be beaten into a sheet covering 100 square feet. It does not tarnish or oxidize.
Field identification & locations
Identify by its characteristic yellow color, extreme density, and malleability. Unlike Pyrite (Fool's Gold), authentic gold will not crush into powder but will flatten when struck.
