Physical properties
Hardness of 7 on the Mohs scale, grayish-blue color, vitreous luster, hexagonal crystal system, conchoidal fracture with no true cleavage.
Formation & geological history
Forms in igneous, metamorphic, and hydrothermal environments through the crystallization of silica-rich solutions.
Uses & applications
Used primarily in lapidary work, jewelry, and crystal collections due to its soothing aesthetic.
Geological facts
The distinct blue color is typically caused by microscopic inclusions of fibrous minerals like crocidolite or dumortierite.
Field identification & locations
Identify by its vitreous luster, lack of cleavage, and high hardness capable of scratching glass; commonly found in pegmatites and metamorphic veins.
