Physical properties
Hardness of 7 on the Mohs scale, vitreous luster, conchoidal fracture, colorless to white with hematite-stained orange/peach areas, hexagonal crystal system.
Formation & geological history
Formed in hydrothermal veins and pegmatites through the precipitation of silica-rich solutions, often incorporating iron oxide inclusions that give the peach or reddish coloration.
Uses & applications
Commonly used in lapidary arts, jewelry, spiritual collections, and decorative items due to its appealing color.
Geological facts
Quartz is one of the most abundant minerals in Earth's continental crust. Varieties colored by iron oxide are often referred to as hematoid quartz or fire quartz.
Field identification & locations
Found worldwide in virtually all geological environments. Identified by its high hardness (scratches glass) and lack of cleavage.
