Physical properties
Hardness of 7 on the Mohs scale, transparent to translucent with a vitreous to greasy luster, trigonal crystal system, conchoidal fracture with no true cleavage, and a specific gravity of 2.65.
Formation & geological history
Formed through hydrothermal precipitation, where silica-rich fluids moved through fractures in the host rock and crystallized within the open spaces, creating a vein structure.
Uses & applications
Used in the manufacturing of glass, ceramics, electronics, precision instruments, and as a raw material for gemstones and mineral collecting.
Geological facts
Quartz is one of the most abundant minerals in Earth's continental crust and is well known for its piezoelectric properties, meaning it generates an electric charge under mechanical stress.
Field identification & locations
Easily identified by its high hardness (scratches glass) and conchoidal fracture. Quartz veins are commonly found traversing metamorphic and igneous host rocks worldwide.
