Physical properties

Formation & geological history

Formed in igneous, metamorphic, and sedimentary geological environments. Commonly crystallizes from silica-rich magmas in pegmatites, hydrothermal veins, or hot springs over millions of years.

Uses & applications

Used widely in electronics (piezoelectric applications), glassmaking, abrasives, jewelry, ornamental carvings, and gemstone collections.

Geological facts

Quartz is the second most abundant mineral in Earth's continental crust. Pure quartz is colorless and transparent, but trace amounts of impurities create various colorful varieties like Rose Quartz, Amethyst, Citrine, and Smoky Quartz.

Field identification & locations

Can be identified in the field by its hardness (scratches glass easily), glassy luster, lack of distinct cleavage, and glassy conchoidal fractures. Commonly found in riverbeds, mountains, pegmatite veins, and gravel pits worldwide.
