Physical properties
Hardness of 7 on the Mohs scale, yellow to golden-brown color, vitreous luster, trigonal crystal system, and conchoidal fracture.
Formation & geological history
Forms in hydrothermal veins, pegmatites, and sedimentary environments through the crystallization of silica-rich solutions over geological timescales.
Uses & applications
Used in jewelry making, ornamental carvings, crystal healing, and electronic oscillator components.
Geological facts
Yellow coloration is typically caused by natural irradiation or sub-microscopic iron hydrate inclusions within the quartz matrix.
Field identification & locations
