Stibnite Naturally Terminated Asia 120g

Mineral Name: Stibnite Chemical Formula: Sb2S3 Color: Stibnite typically appears in a lead-gray to silvery-black color. It may exhibit metallic luster, giving it a shiny and reflective appearance. Crystal System: Orthorhombic Hardness: 2 on the Mohs scale Luster: Metallic Transparency: Opaque Specific Gravity: 4.63 - 4.66 Cleavage: Perfect in one direction, distinct in two other directions Fracture: Uneven to conchoidal Streak: Lead-gray Occurrences: Stibnite is commonly found in hydrothermal veins associated with antimony and other sulfide minerals. It often occurs in association with minerals such as quartz, calcite, and pyrite. Significant deposits have been discovered in China, Bolivia, Peru, Japan, and the United States. Notable Localities: Some notable occurrences of stibnite include the Xikuangshan mine in China, the Ichinokawa mine in Japan, and the Lengenbach Quarry in Switzerland. Formation: Stibnite forms in hydrothermal systems, where hot fluids enriched in antimony and sulfur migrate through fractures in rocks. As these fluids cool, stibnite precipitates from solution, often crystallizing in elongated, needle-like structures. Unique Features: Stibnite is recognized for its distinctive, slender crystal habit, which often forms radiating clusters or long prisms. The crystals can be highly lustrous, giving them a captivating appearance. Stibnite is also known for its relatively low hardness, making it easily identifiable and distinguishable from other minerals. Uses: Stibnite has been historically used as a source of antimony, an element with various industrial applications. Antimony is utilized in the production of flame retardants, alloys, and certain types of batteries. Stibnite specimens are also valued in the mineral collecting community for their unique crystal habits and metallic luster. Caution: Stibnite contains antimony, which, when heated or exposed to certain conditions, can release toxic fumes. Care should be taken when handling or processing stibnite specimens to avoid inhalation of these potentially harmful substances. It is advisable to wash hands thoroughly after handling stibnite and to store specimens in well-ventilated areas.
