Physical properties
Hardness of 7 on the Mohs scale, yellow to golden-brown color, vitreous luster, trigonal crystal system, conchoidal fracture with no true cleavage, specific gravity of 2.65.
Formation & geological history
Forms in hydrothermal veins, pegmatites, and sedimentary environments through the precipitation of silica-rich solutions under varying temperatures and pressures.
Uses & applications
Used in jewelry, decorative carvings, spiritual and metaphysical practices, and as mineral specimens for collectors.
Geological facts
Quartz is one of the most abundant minerals in the Earth's continental crust. Its yellow coloration typically stems from iron impurities or natural irradiation.
Field identification & locations
Can be identified by its high hardness (scratches glass), lack of cleavage, and conchoidal fracture. Found worldwide in various geological settings.
