Physical properties
Hardness of 7 on Mohs scale, colorless or white, vitreous luster, hexagonal crystal system, conchoidal fracture.
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 materials, and as a popular mineral specimen in collections.
Geological facts
Quartz is one of the most abundant minerals in Earth's continental crust and exhibits piezoelectric properties.
Field identification & locations
Identify by its distinct crystal form, high hardness scratching glass, and lack of cleavage; found globally in various geological settings.
