Physical properties
Hardness of 7 on the Mohs scale, clear to translucent color, vitreous luster, hexagonal crystal system, conchoidal fracture with no true cleavage, specific gravity of 2.65.
Formation & geological history
Forms in hydrothermal veins and pegmatites through the cooling and precipitation of silica-rich fluids under high pressure and temperature.
Uses & applications
Commonly used in jewelry making as beads, metaphysical practices, ornamental carvings, and historical artifacts.
Geological facts
Quartz is one of the most abundant minerals in the Earth's continental crust and has been used by humans for millennia to create tools, ornaments, and early lenses.
Field identification & locations
Identified by its high hardness (scratches glass), conchoidal fracture, and glassy luster. Often found worldwide in various geological settings.
