Physical properties
Hardness of 7 on the Mohs scale, white to clear color, vitreous to greasy luster, hexagonal crystal system, conchoidal fracture with no true cleavage, specific gravity of 2.65.
Formation & geological history
Forms in igneous, metamorphic, and sedimentary environments through the cooling of silica-rich solutions or magma.
Uses & applications
Used in electronics, glassmaking, abrasive powders, and as tumbled stones or jewelry.
Geological facts
Quartz is one of the most abundant minerals in the Earth's continental crust and exhibits piezoelectric properties.
Field identification & locations
Identified by its high hardness (scratches glass) and lack of cleavage; globally distributed in pegmatites, veins, and sand.
