Physical properties
Hardness of 7 on the Mohs scale, blue to grayish-blue color, vitreous luster, hexagonal crystal system, and no cleavage.
Formation & geological history
Forms primarily in hydrothermal veins and igneous pegmatites, often colored by microscopic inclusions of dumortierite or crocidolite.
Uses & applications
Used frequently in lapidary arts, tumbled stones, jewelry, and as a collector mineral.
Geological facts
The blue color is typically caused by Rayleigh scattering from minute mineral inclusions rather than structural chemical substitution.
Field identification & locations
Identified by its conchoidal fracture, high hardness, and distinctive blue hue; commonly sourced from Brazil, India, and the USA.
