Physical properties
Hardness of 7 on Mohs scale, vitreous luster, conchoidal fracture, and trigonal crystal system with clear to brown coloration.
Formation & geological history
Formed in a wide range of geological environments, predominantly crystallizing from silicate melts in igneous rocks or precipitating from hydrothermal solutions.
Uses & applications
Used extensively in electronics, glassmaking, precision instruments, abrasive materials, and ornamental jewelry.
Geological facts
Quartz is one of the most abundant and structurally varied minerals found in the Earth's continental crust.
Field identification & locations
Identify by its high hardness (scratches glass), lack of cleavage, and distinct conchoidal fracture found globally in veins and sedimentary sands.
