Physical properties
Hardness of 7 on the Mohs scale, vitreous luster, conchoidal fracture, and hexagonal crystal system. Color varies widely from clear to brown or grey due to impurities.
Formation & geological history
Forms in a wide range of geological environments, prominently crystallizing from hydrothermal veins and cooling magma.
Uses & applications
Used extensively in electronics, glassmaking, precision instruments, and as gemstone or specimen material.
Geological facts
Quartz is one of the most abundant and widely distributed minerals found on Earth's continental crust.
Field identification & locations
Identified easily by its distinct crystal habit and high hardness which scratches glass easily. Found globally in almost all rock types.
