Native silver (probable)

Elemental silver, Ag, likely with oxidized sulfide or copper minerals

AI-generated identification · may be incorrect

A tiny irregular metallic-gray to silver-white specimen with porous, spongy texture and dark cavities; native silver is malleable, opaque, and has metallic luster, Mohs hardness 2.5–3, cubic crystal structure, and no cleavage. The image alone cannot confirm composition;…

Physical properties

Formation & geological history

Native silver forms in hydrothermal veins and oxidation zones, commonly with quartz, calcite, galena, and silver sulfides; deposits range from Precambrian to modern geological ages. Its porous texture may reflect weathering or dissolution of associated minerals.

Uses & applications

Historically used for coinage, electronics, solder, mirrors, photography, and jewelry; attractive native specimens are collectible. Industrial value depends mainly on assayable silver content.

Geological facts

Silver tarnishes gray or black through sulfur-bearing reactions and is unusually ductile. A streak test, density measurement, and X-ray fluorescence or chemical assay are needed for reliable identification.

Field identification & locations

Common sources include Mexico, Peru, Bolivia, Canada, the United States, and Australia. Test cautiously: native silver leaves a silvery streak and is easily cut or bent; avoid destructive acid testing without expertise.
