Physical properties
Hardness of 7 on the Mohs scale, vitreous luster, hexagonal crystal system, conchoidal fracture, and specific gravity of 2.65.
Formation & geological history
Forms in hydrothermal veins, pegmatites, and sedimentary environments through the crystallization of silica-rich solutions over millions of years.
Uses & applications
Used widely in jewelry, as tumbled decorative stones, crystal healing, and in electronics for its piezoelectric properties.
Geological facts
Yellow coloration is typically caused by natural irradiation or iron oxide inclusions within the silica matrix.
Field identification & locations
Identifiable by its inability to be scratched by steel and its distinct conchoidal fracture; found worldwide in diverse geological settings.
