Physical properties

Hardness of 7 on the Mohs scale, blue color due to microscopic inclusion fibers, vitreous luster, trigonal crystal system, and conchoidal fracture.

Formation & geological history

Forms in hydrothermal veins and igneous or metamorphic rocks through the inclusion of minerals like tourmaline or crocidolite during crystallization.

Uses & applications

Used primarily in jewelry, gemstone carving, ornamental objects, and crystal healing practices.

Geological facts

The blue color is usually an optical effect caused by Rayleigh scattering from tiny inclusions rather than structural chemical coloring.

Field identification & locations

Identify by its hardness scratching glass, greasy to vitreous luster, and lack of cleavage. Commonly sourced from Brazil, India, and the USA.
