Physical properties
Hardness of 7 on the Mohs scale, transparent to translucent with vitreous luster, and forms in the trigonal crystal system with conchoidal fracture.
Formation & geological history
Forms hydrothermally in igneous, metamorphic, and sedimentary environments over millions of years as silica-rich fluids cool and precipitate.
Uses & applications
Widely used in electronics, oscillator manufacturing, glass production, ornamental items, and jewelry.
Geological facts
Quartz is the second most abundant mineral in Earth's continental crust and exhibits piezoelectric properties, generating an electric charge under mechanical stress.
Field identification & locations
Easily identified by its characteristic crystal shape, high hardness that scratches glass, and lack of cleavage. Found worldwide.
