Physical properties
Hardness of 7 on the Mohs scale, vitreous luster, sub-rounded to sub-angular habit, and transparent to translucent white/colorless.
Formation & geological history
Formed via weathering, erosion, and transport of silica-rich igneous, metamorphic, or sedimentary rocks across sedimentary environments.
Uses & applications
Essential in glass manufacturing, construction aggregate, silicon chip production, and filtration media.
Geological facts
Quartz is one of the most mechanically and chemically durable minerals on Earth's surface, allowing grains to survive millions of years of abrasive transport.
Field identification & locations
Identifiable by its glassy luster, inability to be scratched by steel, and pervasive presence in sand dunes, beaches, and riverbeds worldwide.
