Physical properties
Small, translucent to whitish fragment with a glassy luster; quartz has Mohs hardness 7, a trigonal crystal structure, no true cleavage, and conchoidal fracture. The photo is not detailed enough to confirm identification.
Formation & geological history
Quartz forms in many igneous, metamorphic, and sedimentary settings as magma cools or silica-rich fluids crystallize; it occurs across a vast range of geological ages.
Uses & applications
Quartz is used in glassmaking, electronics, abrasives, and jewelry; this tiny, irregular fragment has little practical or jewelry value.
Geological facts
Quartz is one of Earth’s most abundant minerals and is often confused with glass; unlike glass, it can scratch ordinary window glass.
Field identification & locations
Look for glassy luster, lack of cleavage, and hardness sufficient to scratch glass. Quartz occurs worldwide in veins, pegmatites, and many rocks.
