Physical properties
Hardness of 7 on the Mohs scale, white to translucent color, vitreous luster, trigonal crystal system, conchoidal fracture with no true cleavage, and specific gravity around 2.65.
Formation & geological history
Formed through crystallization from silica-rich hydrothermal solutions or cooling magmas, widely found in igneous, metamorphic, and sedimentary rocks across all geological eras.
Uses & applications
Used in electronics, glassmaking, abrasives, decorative items, and as a gemstone in jewelry.
Geological facts
Quartz is the second most abundant mineral in Earth's continental crust and exhibits strong piezoelectric properties.
Field identification & locations
Easily identified by its high hardness (scratches glass) and lack of cleavage, commonly found in river gravels, veins, and pegmatites worldwide.
