Stannite is a copper iron tin sulfide mineral that occurs in metallic to submetallic masses with a brassy to grey color and an opaque lustre. It often forms in arsenopyrite-bearing hydrothermal veins and contact metamorphic environments, and it can appear in coarse grains or intergrown with other sulfides. Specimens are valued for their reflective surfaces and the contrast with associated sulfides, as well as their occurrence in well-known ore districts.

All guidesAbout Stannite
Notable localities producing well-crystallized material include Bolivia, China, Portugal, Argentina, and the United Kingdom, where stannite often occurs with sulfides in steeply dipping veins and skarns. Collectors prize clean, well-formed crystals or attractive aggregates that showcase its metallic sheen and subtle color zoning. While the mineral can be associated with tin and copper ore deposits, its aesthetic appeal and relative rarity in good crystal form make it a sought-after specimen for display and study.
