Physical properties
Hardness 7 on Mohs scale, vitreous luster, blue to gray coloration with pinkish-orange orthoclase inclusions, conchoidal fracture, specific gravity around 2.65.
Formation & geological history
Formed through slow crystallization of silica-rich magma deep within the Earth's crust, commonly found in pegmatites and granitic rocks.
Uses & applications
Used primarily as mineral specimens for collectors, decorative lapidary items, and sometimes in metaphysical practices.
Geological facts
The blue color in quartz is typically caused by microscopic inclusions of dumortierite or tiny rutile needles that scatter light via Rayleigh scattering.
Field identification & locations
Easily identified by its distinct blue hue embedded with pinkish feldspar grains; commonly located in glaciated Canadian Shield regions matching the given coordinates.
