Tetrahedrite with quartz is a fascinating mineral combination that commonly form together in hydrothermal vein deposits. These deposits form from mineral-rich hot waters circulating through fractures and voids in rocks, depositing minerals as they cool and react with the surrounding rock.
Tetrahedrite crystallizes in the isometric crystal system, typically forming tetrahedral or dodecahedral crystals. It can also appear in massive or granular forms. Tetrahedrite is a complex sulfosalt mineral with the general formula (Cu,Fe)₁₂Sb₄S₁₃. It can contain varying amounts of copper, iron, zinc, silver, and other metals, which can substitute within its structure.
Tetrahedrite typically appears metallic gray to black. It has a metallic luster and can tarnish to a darker color over time. Quartz is typically colorless or white but can also be found in a variety of colors depending on impurities. In association with tetrahedrite, it often appears as clear or milky quartz.
Peru is particularly well-known for producing beautiful specimens, as follows Mexico, US and other locations globally.
