Physical properties
Hardness of 7 on the Mohs scale, blue color due to microscopic inclusions, vitreous luster, hexagonal crystal system, and no cleavage.
Formation & geological history
Forms in igneous, metamorphic, and sedimentary environments through the crystallization of silica-rich solutions with mineral inclusions.
Uses & applications
Used primarily in jewelry, lapidary arts, and as a decorative stone or mineral specimen for collectors.
Geological facts
The blue color is typically caused by Rayleigh scattering from microscopic fibrous inclusions like dumortierite or crocidolite.
Field identification & locations
Identified by its distinct blue hue, conchoidal fracture, and high hardness; commonly found in pegmatites and hydrothermal veins worldwide.
