Physical properties
Hardness of 7 on the Mohs scale, milky white to translucent color, vitreous to greasy luster, trigonal crystal system, conchoidal fracture with no true cleavage, specific gravity of 2.65.
Formation & geological history
Forms in a wide variety of geological environments, most notably in igneous rocks like granite and pegmatites, as well as hydrothermal veins and metamorphic rocks.
Uses & applications
Commonly used in jewelry as carved or polished pendants, decorative items, and lapidary arts.
Geological facts
Quartz is one of the most abundant minerals found in the Earth's continental crust and exhibits piezoelectric properties, meaning it can generate an electrical charge under mechanical stress.
Field identification & locations
Easily identified by its hardness (scratches glass), lack of cleavage, and distinct conchoidal fracture. Found globally.
