Physical properties
Hardness of 7 on the Mohs scale, transparent to translucent with a vitreous luster, hexagonal crystal system, and conchoidal fracture with no true cleavage.
Formation & geological history
Forms in igneous, metamorphic, and sedimentary environments through cooling magma or precipitation from silica-rich hydrothermal solutions.
Uses & applications
Widely used in electronics, glassmaking, precision instruments, and as a gemstone or ornamental carving material.
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
Identified easily by its high hardness (scratches glass), lack of cleavage, and distinct hexagonal crystal habit when well-formed.
