Physical properties
Hardness of 7 on the Mohs scale, transparent to translucent color, vitreous luster, hexagonal crystal system, and conchoidal fracture with no cleavage.
Formation & geological history
Forms in hydrothermal veins, pegmatites, and as a primary component of igneous, metamorphic, and sedimentary rocks over millions of years.
Uses & applications
Widely used in jewelry, electronics for frequency control, glassmaking, and metaphysical crystal collecting.
Geological facts
Clear quartz is the most abundant mineral found at Earth's surface and exhibits piezoelectric properties, generating electric charges under mechanical stress.
Field identification & locations
Easily identified by its high hardness (scratches glass), lack of cleavage, and transparent tumbled or crystalline appearance.
