Physical properties
Mohs hardness of 7, yellow color due to iron impurities, vitreous luster, trigonal crystal system, and conchoidal fracture.
Formation & geological history
Forms in hydrothermal veins and pegmatites through the precipitation of silica-rich solutions at low to high temperatures.
Uses & applications
Used in jewelry, metaphysical healing practices, and mineral collections.
Geological facts
Naturally yellow quartz is often confused with citrine, though many commercial citrines are actually heat-treated amethyst.
Field identification & locations
Identified by its distinct yellow coloration, high hardness scratching glass, and lack of cleavage.
