Physical properties
Hardness of 7 on the Mohs scale, blue color due to microscopic inclusion fibers, vitreous luster, hexagonal crystal system, and no cleavage.
Formation & geological history
Forms in igneous, metamorphic, and hydrothermal environments through the crystallization of silica-rich solutions with mineral inclusions.
Uses & applications
Used primarily in jewelry, tumbling, metaphysical practices, and ornamental carvings.
Geological facts
The blue color is typically caused by Rayleigh scattering from microscopic inclusions of rutile, tourmaline, or dumortierite.
Field identification & locations
Identify by its conchoidal fracture, high hardness scratching glass, and characteristic blue hue; commonly found in Brazil, India, and the USA.
