Physical properties
Hardness: 7 on Mohs scale (quartz), Color: White, pinkish-red, and grey, Luster: Vitreous to greasy, Crystal Structure: Trigonal (quartz), Cleavage: None (conchoidal fracture), Specific Gravity: 2.65
Formation & geological history
Formed through hydrothermal processes where silica-rich fluids crystallized within fractures of older host rocks, very common globally.
Uses & applications
Used in landscaping, ornamental stone, aggregate, and as a mineral specimen for collectors.
Geological facts
Quartz is one of the most abundant minerals in the Earth's continental crust and is exceptionally resistant to weathering.
Field identification & locations
Easily identified by its high hardness (scratches glass) and conchoidal fracture. Commonly found in veins cutting through various rock types.
