Physical properties
Hardness: 7 on Mohs scale. Color: Clear to milky with dark inclusions. Luster: Vitreous (glassy). Crystal structure: Trigonal. Cleavage: None, exhibits conchoidal fracture. Specific gravity: 2.65.
Formation & geological history
Forms in hydrothermal veins, pegmatites, and as a primary mineral in igneous, metamorphic, and sedimentary rocks over millions of years.
Uses & applications
Used in gemstone collection, lapidary arts, metaphysical practices, and scientific specimens.
Geological facts
Quartz is one of the most abundant minerals in the Earth's continental crust and frequently hosts other minerals as inclusions during its growth.
Field identification & locations
Easily identified by its hardness (scratches glass) and conchoidal fracture. Commonly found worldwide in various geological environments.
