Physical properties
Hardness of 7 on the Mohs scale; milky white to translucent color; vitreous to greasy luster; trigonal crystal system; conchoidal fracture with no true cleavage; specific gravity of 2.65.
Formation & geological history
Formed through the crystallization of silica-rich hydrothermal solutions or cooling magma in pegmatites, veins, and various rock types worldwide over millions of years.
Uses & applications
Used in glassmaking, electronics, abrasives, ornamental items, and crystal collecting.
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 hardness (scratches glass), lack of cleavage, and conchoidal fracture. Common in almost all geological environments.
