Physical properties
Hardness of 7 on the Mohs scale, blue to grayish-blue color due to microscopic inclusion fibers, vitreous luster, hexagonal crystal system, and conchoidal fracture with no true cleavage.
Formation & geological history
Forms primarily in hydrothermal veins and pegmatites, as well as igneous and metamorphic rocks, often colored by dumortierite or riebeckite inclusions.
Uses & applications
Used primarily in ornamental carvings, gemstone jewelry, and metaphysical collections.
Geological facts
The blue color is usually an optical effect caused by inclusions rather than the quartz lattice itself.
Field identification & locations
Identify by its vitreous luster, conchoidal fracture, high hardness, and distinctive blue coloration. Commonly found in Brazil, India, and the USA.
