Physical properties
Hardness of 7 on the Mohs scale, transparent to opaque, vitreous luster, hexagonal crystal system, and no cleavage.
Formation & geological history
Forms in a wide range of geological environments, including igneous, metamorphic, and sedimentary rocks, often through crystallization from silica-rich hydrothermal solutions.
Uses & applications
Used extensively in electronics, glassmaking, precision instruments, and as a gemstone or ornamental carving material.
Geological facts
Quartz is one of the most abundant and widely distributed minerals found on Earth's continental crust.
Field identification & locations
Easily identified by its distinct conchoidal fracture, high hardness, and lack of reactivity to acid; commonly found in pegmatites, veins, and sandstones globally.
