Physical properties
Mohs hardness of 7, glassy to vitreous luster, hexagonal crystal system, no cleavage, conchoidal fracture, translucent yellow to honey-brown color.
Formation & geological history
Formed through igneous crystallization in hydrothermal veins and pegmatites, or via heat exposure to iron-bearing quartz crystals.
Uses & applications
Used extensively as decorative gemstone carvings, tumbled stones, jewelry, and popular among crystal collectors and metaphysical enthusiasts.
Geological facts
Quartz is the second most abundant mineral in Earth's continental crust. Yellow varieties often derive their warm color from iron oxide inclusions or natural irradiation.
Field identification & locations
Can be identified in the field by its hardness (scratches glass readily, cannot be scratched by steel), lack of cleavage, and characteristic greasy to vitreous luster. Commonly found in Brazil, Madagascar, and the USA.
