Physical properties
Hardness of 7 on the Mohs scale. Color is colorless or transparent. Vitreous (glass-like) luster. Crystal system is trigonal, typically forming hexagonal prisms terminating in six-sided pyramids. Conchoidal fracture, no distinct cleavage, specific gravity of 2.65.
Formation & geological history
Formed from silicon and oxygen rich hydrothermal solutions in pegmatites, veins, and cavities in various rock types over millions of years.
Uses & applications
Used in jewelry, decorative items, oscillators in electronics, watches, and piezoelectric applications.
Geological facts
Known as the 'Master Healer' in crystal healing traditions, clear quartz is one of the most abundant minerals on Earth and exhibits strong piezoelectric properties.
Field identification & locations
Identified by its hexagonal crystal habit, high hardness (scratches glass), and vitreous luster. Found worldwide, notably in Brazil, Arkansas (USA), Madagascar, and the Alps.
