Rounded greenish-gold rock or mineral pebble
Indeterminate; possibly serpentine-rich stone, weathered sulfide, or iron-stained metamorphic rock
AI-generated identification · may be incorrectOlive-green to yellow-brown, dull to slightly earthy luster, and rounded from abrasion; hardness, cleavage, crystal structure, and specific gravity cannot be reliably determined from the image. The metallic-looking color is not sufficient to identify native gold or pyrite.

Physical properties
Olive-green to yellow-brown, dull to slightly earthy luster, and rounded from abrasion; hardness, cleavage, crystal structure, and specific gravity cannot be reliably determined from the image. The metallic-looking color is not sufficient to identify native gold or pyrite.
Formation & geological history
Likely a naturally weathered and water-worn geological fragment; its precise formation age and environment require tests such as streak, hardness, density, magnetism, and fresh-surface examination.
Uses & applications
No confirmed industrial or jewelry use without identification; attractive pebbles may be kept as curiosities or used in collections and crafts.
Geological facts
Color and rounded shape can result from serpentine, limonite/goethite, altered basalt, or sulfide minerals. Native gold is usually much denser, more metallic, and distinctly malleable.
Field identification & locations
Field identification requires checking streak on unglazed porcelain, hardness against glass, heft/density, magnetism, and whether a knife scratches it; avoid acid testing without guidance. Common possibilities occur in stream gravels and weathered ultramafic or mineralized terrains.
