Physical properties
Hardness 7 on Mohs scale, grayish-blue color, vitreous luster, hexagonal crystal system, conchoidal fracture.
Formation & geological history
Forms in hydrothermal veins and igneous or metamorphic rocks through the inclusion of microscopic fibrous minerals like dumortierite.
Uses & applications
Used primarily in lapidary work, jewelry making, and as a decorative mineral specimen for collectors.
Geological facts
The distinct blue hue is typically caused by Rayleigh scattering from tiny mineral inclusions trapped inside the quartz matrix during growth.
Field identification & locations
Identified by its high hardness, conchoidal fracture, and characteristic blue-gray coloration; commonly found in pegmatites and hydrothermal veins worldwide.
