Physical properties
Hardness of 7 on the Mohs scale, yellow to golden color, vitreous luster, hexagonal crystal system, and conchoidal fracture with no true cleavage.
Formation & geological history
Forms primarily in hydrothermal veins and pegmatites through the precipitation of silica-rich solutions under high temperature and pressure.
Uses & applications
Used in jewelry, metaphysical healing practices, decorative carvings, and mineral collections.
Geological facts
The yellow coloration in quartz is typically caused by natural irradiation acting on aluminum impurities within the crystal lattice.
Field identification & locations
Identified by its distinct yellow hue, high scratch resistance against steel, and lack of cleavage; found globally in quartz-rich pegmatites and alluvial deposits.
