Native gold specimen

Native gold (Au), likely with quartz or sulfide matrix

AI-generated identification · may be incorrect

Small metallic yellow-gold aggregate with bright luster and irregular crystalline texture. Gold has Mohs hardness 2.5–3, cubic crystal structure, no cleavage, and very high specific gravity (~19.3); it is malleable rather than brittle.

Physical properties

Formation & geological history

Forms hydrothermally in quartz veins and sulfide-rich ores, or concentrates as placer gold through weathering and stream transport. Gold deposits range from ancient Precambrian to geologically recent placer environments.

Uses & applications

Used chiefly in jewelry, electronics, dentistry, and investment; natural specimens are collectible. The visible piece may be worth more than melt value if its authenticity and form are verified.

Geological facts

Gold’s distinctive yellow color remains consistent in shade, unlike pyrite, which is harder and brittle. A typical specimen this small may contain only a fraction of a gram.

Field identification & locations

Common sources include Australia, Alaska, California, Nevada, Canada, and South Africa. Confirm with density, malleability, streak, and ideally a professional XRF test; pyrite and chalcopyrite are common look-alikes.
