Physical properties
Hardness of 7 on the Mohs scale, yellow to golden color, vitreous luster, trigonal crystal system, conchoidal fracture, specific gravity of 2.65.
Formation & geological history
Formed in hydrothermal veins and pegmatites through the precipitation of silica-rich solutions under high pressure and temperature over millions of years.
Uses & applications
Used in jewelry, decorative items, and mineral collecting.
Geological facts
The yellow coloration is often due to iron oxide impurities trapped within the quartz matrix during crystallization.
Field identification & locations
Can be identified by its hardness (scratches glass), lack of cleavage, and vitreous luster. Found worldwide in various geological settings.
