Physical properties
Hardness of 7 on the Mohs scale, vitreous luster, conchoidal fracture, and hexagonal crystal system. Color ranges from clear and white to pink, yellow, and brown.
Formation & geological history
Forms in igneous, metamorphic, and sedimentary environments through crystallization from silica-rich melts and hydrothermal solutions.
Uses & applications
Used in electronics, glassmaking, abrasives, and as a popular gemstone and lapidary material.
Geological facts
Quartz is the second most abundant mineral in Earth's continental crust and exhibits strong piezoelectric properties, making it essential for clocks and oscillators.
Field identification & locations
Identified easily by its high hardness (scratches glass), lack of cleavage, and conchoidal fracture. Found worldwide in nearly all geological settings.
