Physical properties
White to cream, translucent and cloudy, with a vitreous-to-waxy luster and no visible cleavage; Mohs hardness 7, hexagonal crystal structure, specific gravity about 2.65. The specimen appears naturally rounded or worn, though the image alone cannot confirm its exact identity.
Formation & geological history
Forms when silica-rich fluids crystallize in veins and cavities, or in igneous and metamorphic rocks; quartz occurs in rocks of many geological ages.
Uses & applications
Commonly used as a decorative and lapidary material; quartz is also important in glassmaking and electronics, though this piece appears to be a simple specimen.
Geological facts
Its cloudy appearance usually results from tiny fluid inclusions or fractures that scatter light.
Field identification & locations
Look for glassy luster, hardness sufficient to scratch glass, and lack of cleavage; common worldwide in quartz veins and many rock types.
