# How to identify silver Canonical page: https://lithomap.app/resources/mineral-identification/silver Last reviewed: September 17, 2026 Page purpose: Original LithoMap mineral identification reference for field observations, search systems, and language models. Classification: Native element · Ag ## Summary Native silver is a dense, soft, malleable metal with a bright silver-white fresh surface that commonly tarnishes gray, brown, or black; it occurs in wires, plates, grains, and irregular masses. ## Quick identification clues - Bright silver-white metal on a fresh surface - Mohs hardness about 2.5 to 3 - Malleable and sectile, not brittle - Very dense and commonly darkly tarnished ## Composition and classification Native silver is elemental Ag and may contain gold, copper, mercury, or other metals. Natural silver also occurs in many sulfide, sulfosalt, halide, and telluride minerals, so a silver-bearing specimen is not necessarily native silver. ## Appearance Fresh native silver has a bright metallic white color, but exposure can produce gray to black tarnish that conceals it. Wires, curls, branching aggregates, plates, and compact masses are characteristic forms. Thin coatings, metallic lead, galena, and manufactured metal can look similar. Visual appearance alone cannot establish elemental silver, fineness, or economic value. ## Identification tests - Hardness: 2.5 to 3. Scratched by copper or steel; much softer than pyrite. - Streak: Silver-white. Differs from galena’s gray-black streak, although tarnish can interfere. - Tenacity: Malleable, ductile, and sectile. A loose expendable piece deforms instead of breaking like galena. - Density: Very high; specific gravity about 10.5. Heft supports identification but does not distinguish every heavy metal. ## Common lookalikes - Galena: Brittle, gray-streaked, and breaks along cubic cleavage instead of bending. - Native lead: Darker, softer, and commonly associated with human-made material; context and analysis may be required. - Manufactured metal: Solder, foil, wire, and fragments often have regular shapes or occur near human activity. ## Direct side-by-side comparisons - Silver vs. galena — https://lithomap.app/resources/mineral-identification/compare/silver-vs-galena ## Most relevant related guides - Galena — https://lithomap.app/resources/mineral-identification/galena - Apatite — https://lithomap.app/resources/mineral-identification/apatite - Augite — https://lithomap.app/resources/mineral-identification/augite - Azurite — https://lithomap.app/resources/mineral-identification/azurite ## Formation Native silver forms in hydrothermal veins, enriched zones of silver-bearing deposits, and some volcanic or sediment-hosted systems where chemical conditions allow elemental metal to precipitate. It may occur with native copper and gold, calcite, quartz, galena, acanthite, cobalt-nickel minerals, and other ore minerals. ## Occurrence and geologic setting Native silver is uncommon compared with silver hosted in other minerals. Even a productive silver deposit may contain little visible native metal. Dark tarnish and small grain size make field recognition difficult. Laboratory analysis is appropriate before appraisal, processing, or claims about composition. ## Uses and significance Silver is used in electronics, solar cells, brazing alloys, mirrors, antimicrobial applications, photography, jewelry, tableware, and investment products. ## Field safety and limitations - Do not use acids or improvised chemical tests on suspected silver. - Lead- and arsenic-bearing minerals commonly occur in silver deposits; avoid dust and wash hands. - Field appearance cannot establish fineness, authenticity, provenance, or value. ## Authoritative sources - Silver Statistics and Information — U.S. Geological Survey: https://www.usgs.gov/centers/national-minerals-information-center/silver-statistics-and-information - Minerals and their physical properties — U.S. National Park Service: https://www.nps.gov/subjects/geology/minerals.htm - Mohs Hardness Scale — U.S. National Park Service: https://www.nps.gov/articles/mohs-hardness-scale.htm - Natural Gemstones: Mineral Gemstones — U.S. Geological Survey: https://pubs.usgs.gov/gip/gemstones/mineral.html ## Specimen photograph - Image: https://lithomap.app/_delivery/identification/minerals/silver.webp - Description: Tarnished gray native silver in a quartz matrix from near Cobalt, Ontario - Creator: Darla Sondrol - License: CC0 1.0 — https://creativecommons.org/publicdomain/zero/1.0/ - Source record: https://commons.wikimedia.org/wiki/File:Native_silver_(GeoDIL_number_-_883).jpg This reference supports preliminary field identification.
