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, specific gravity of 2.65.
Formation & geological history
Forms in all types of environments—igneous, metamorphic, and sedimentary—often precipitating from hydrothermal solutions or crystallizing from cooling magma.
Uses & applications
Used in electronics, glassmaking, abrasive materials, ornamental objects, and crystal healing or mineral collecting.
Geological facts
Quartz is one of the most abundant and widely distributed minerals found on Earth's continental crust, known for its piezoelectric properties.
Field identification & locations
Easily identified by its lack of cleavage, high hardness (scratches glass), and characteristic conchoidal fracture. Found worldwide.
