Physical properties
Hardness of 7 on the Mohs scale, milky white color, vitreous to greasy luster, trigonal crystal system, conchoidal fracture with no true cleavage.
Formation & geological history
Forms in igneous, metamorphic, and sedimentary environments through crystallization from silica-rich hydrothermal solutions and magmas.
Uses & applications
Widely used in electronics, glass manufacturing, abrasives, and ornamental jewelry or crystal collecting.
Geological facts
Quartz is one of the most abundant minerals in the Earth's continental crust and exhibits strong piezoelectric properties.
Field identification & locations
Identified easily by its high hardness (scratches glass), lack of cleavage, and characteristic conchoidal fracture; found globally.
