Physical properties
Mohs hardness of 7; colorless or white; vitreous luster; hexagonal crystal system; conchoidal fracture with no true cleavage.
Formation & geological history
Formed via hydrothermal veins and pegmatites through the precipitation of silica-rich solutions over geological timescales.
Uses & applications
Used in electronics, oscillators, glassmaking, abrasive powders, and as a popular mineral specimen in lapidary arts.
Geological facts
Quartz is the second most abundant mineral in Earth's continental crust and exhibits strong piezoelectric properties.
Field identification & locations
Easily identified by its distinct hexagonal prism habit, high hardness, and resistance to weathering in diverse geological settings.
