Physical properties
Translucent, colorless to milky, with a vitreous luster; hardness 7 Mohs, trigonal crystal system, and no true cleavage. The small, blocky shape and reflections make exact identification uncertain from the photo.
Formation & geological history
Quartz forms in igneous and metamorphic rocks and in hydrothermal veins, crystallizing from silica-rich melts or fluids over geologic time.
Uses & applications
Quartz is used in glass, electronics, abrasives, and jewelry; this tiny fragment has mainly modest collecting or craft value.
Geological facts
Quartz is one of Earth’s most abundant minerals and commonly occurs in many rock types.
Field identification & locations
Look for glassy luster, hardness sufficient to scratch glass, and conchoidal fracture; common worldwide in veins, granites, and pegmatites.
