Physical properties
White to translucent, vitreous luster, massive and irregular; Mohs hardness 7, no cleavage, uneven to conchoidal fracture. The photo is consistent with quartz, though visual identification alone is not definitive.
Formation & geological history
Forms when silica-rich fluids or melts crystallize, commonly in veins and pegmatites; its exact age and locality cannot be determined from the image.
Uses & applications
Used as a decorative and collectible mineral; quartz is also an important source material for glass and engineered stone.
Geological facts
Milky appearance results from microscopic fluid or gas inclusions that scatter light.
Field identification & locations
Look for glassy luster, hardness sufficient to scratch ordinary glass, and lack of cleavage; common worldwide in quartz veins and many igneous and metamorphic rocks.
