Physical properties
Hardness of 7 on the Mohs scale, white or milky color, vitreous to greasy luster, trigonal crystal system, and conchoidal fracture with no true cleavage.
Formation & geological history
Forms primarily from cooling magma in igneous pegmatites or via hydrothermal veins and low-temperature precipitation in sedimentary environments.
Uses & applications
Used widely in glassmaking, electronics, abrasives, and as a popular tumbled stone or gemstone in jewelry.
Geological facts
Quartz is one of the most abundant and durable minerals in Earth's continental crust, highly resistant to both chemical and mechanical weathering.
Field identification & locations
Easily identified by its high hardness of 7, lack of cleavage, and distinct conchoidal fracture; found worldwide in almost all geological environments.
