Physical properties
Hardness of 7 on the Mohs scale, vitreous luster, hexagonal crystal system, and uneven fracture. Color ranges from pale to deep blue due to microscopic mineral inclusions.
Formation & geological history
Forms in hydrothermal veins, pegmatites, and metamorphic environments through the incorporation of fibrous blue silicate minerals during crystallization.
Uses & applications
Widely used in ornamental carvings, polished tumbling stones, jewelry, and crystal collections.
Geological facts
The blue color is typically allochromatic, caused by light scattering or sub-microscopic inclusions rather than intrinsic elemental substitution.
Field identification & locations
Identified by its conchoidal fracture, high scratch resistance, and distinct blue coloration. Commonly sourced from Brazil, India, and the USA.
