Native Silver
Native Silver · Mineral Specimen and Precious Metal
Crystal System
Cubic (Isometric), commonly occurring in dendritic, wire, or massive habits
Mineral Group
Native Elements
Chemical Formula
Ag
Formation Process
Hydrothermal deposition from metal-rich aqueous solutions at low to moderate temperatures, or through secondary enrichment processes
About This Crystal
The specimen exhibits a metallic, silvery-grey to tarnished dark grey surface with a dendritic or massive habit, showing characteristic uneven textures and bright metallic highlights where freshly exposed
Physical Characteristics
Silver-white body color often tarnishing to dark grey or black, metallic luster, streak is silver-white and shiny, perfect cleavage is absent, hackly fracture, specific gravity is approximately 10.5, highly malleable and ductile, and sectile
Optical Properties
Opaque with a strong metallic luster, highly reflective surface showing bright specular highlights, isotropic in reflected light
Hardness & Durability
Origin Region
Notable sources include Kongsberg (Norway), Michigan (USA), and various locations in Mexico and Canada, typically found in hydrothermal veins and native deposits
Hardness & Durability
Mohs hardness of 2.5 to 3, highly malleable and ductile, very soft, lacks toughness for heavy-wear jewelry but can be used in protective settings
Care & Maintenance
Clean with warm soapy water and a soft cloth, avoid harsh chemical dips that strip the natural patina unless necessary, store in a dry environment away from sulfur compounds to prevent rapid tarnishing
Rarity & Value
Uncommon as well-formed mineral specimens, value is determined by specimen aesthetics, crystal form, size, and silver market value, ranging from modest to high collector prices
Special Characteristics
High electrical and thermal conductivity, excellent reflectivity, and prone to developing a dark silver-sulfide tarnish when exposed to atmospheric sulfur
Lore & History
Historically associated with the Moon and lunar energies in ancient alchemical traditions, valued for centuries as a precious metal currency and ornamental material, and traditionally believed by crystal practitioners to enhance emotional balance and communication
