Physical properties
Hardness of 7 on the Mohs scale, transparent to translucent with a vitreous luster, hexagonal crystal system, no true cleavage, and a specific gravity of 2.65. The specimen is whitish or clear and crystalline.
Formation & geological history
Forms in a wide variety of geological environments, most commonly in igneous rocks like granite and pegmatites, as well as hydrothermal veins and sedimentary deposits. It is extremely resistant to weathering.
Uses & applications
Widely used in electronics, oscillators, glassmaking, abrasives, and as a popular gemstone or specimen for crystal collectors.
Geological facts
Quartz is one of the most abundant and widely distributed minerals found on Earth's continental crust. Its piezoelectric properties make it essential for modern electronics, watches, and radio transmitters.
Field identification & locations
Identified by its high hardness (scratches glass), lack of cleavage, and typical crystal habit or granular crystalline texture. Found globally in almost all types of rock formations.
