Physical properties
Hardness of 7 on Mohs scale, blue to grayish-blue color, vitreous luster, hexagonal crystal system, conchoidal fracture with no true cleavage.
Formation & geological history
Forms primarily in igneous and metamorphic environments, often colored blue by microscopic inclusions of dumortierite or riebeckite fibers.
Uses & applications
Used in ornamental jewelry, lapidary arts, and as mineral specimens for collectors.
Geological facts
The blue color is typically an optical effect or caused by inclusions rather than elemental substitution within the quartz lattice.
Field identification & locations
Identified by its high hardness, conchoidal fracture, and distinct blue coloration; commonly found in pegmatites and hydrothermal veins.
