Physical properties
Hardness of 7 on the Mohs scale, white or milky color, vitreous to greasy luster, trigonal crystal system, and lacks cleavage with conchoidal fracture.
Formation & geological history
Formed through hydrothermal processes or crystallization in igneous and metamorphic environments, subsequently rounded by water transport in sedimentary streams.
Uses & applications
Used in landscaping, decorative gravel, glassmaking, and abrasive manufacturing.
Geological facts
Quartz is one of the most abundant minerals in Earth's continental crust and exhibits piezoelectric properties.
Field identification & locations
Easily identified by its high hardness (scratches glass), white color, and lack of reaction to acid; commonly found in riverbeds and beaches worldwide.
