Physical properties
Mohs hardness of 7, white or milky color, vitreous to greasy luster, trigonal crystal system, and conchoidal fracture.
Formation & geological history
Forms in igneous, metamorphic, and sedimentary environments through the cooling of silica-rich fluids or crystallization of magma.
Uses & applications
Used in electronics, glassmaking, abrasive powders, and ornamental jewelry or crystal collections.
Geological facts
Quartz is one of the most abundant minerals in Earth's continental crust and exhibits strong piezoelectric properties.
Field identification & locations
Easily identified by its high hardness (scratches glass) and lack of cleavage; found globally in veins, pegmatites, and sands.
