Physical properties
Hardness of 7 on the Mohs scale, blue to grayish-blue color, vitreous luster, hexagonal crystal system, and poor cleavage.
Formation & geological history
Forms in hydrothermal veins and pegmatites through the inclusion of microscopic fibrous minerals like crocidolite or dumortierite during crystallization.
Uses & applications
Used primarily in lapidary work, jewelry, and crystal healing practices.
Geological facts
The distinct blue coloration is typically caused by Rayleigh scattering from microscopic inclusions rather than the quartz crystal lattice itself.
Field identification & locations
Identified by its conchoidal fracture, high scratch resistance, and characteristic blue hue; commonly found in Brazil, India, and the USA.
