Physical properties
Small, rough, translucent-white fragment with a vitreous to dull luster; quartz has Mohs hardness 7, a hexagonal crystal structure, no cleavage, and conchoidal fracture. The image is too small to confirm identification or measure specific gravity.
Formation & geological history
Quartz crystallizes from silica-rich fluids in veins and igneous rocks, and also occurs in metamorphic and sedimentary settings; its age depends on the host deposit.
Uses & applications
Quartz is used in glassmaking, electronics, construction, and jewelry; this tiny fragment has little practical or jewelry value.
Geological facts
Quartz is one of Earth’s most abundant minerals and commonly occurs as milky, cloudy crystals when fluid inclusions or defects scatter light.
Field identification & locations
Look for hardness sufficient to scratch glass, lack of cleavage, and irregular curved fracture surfaces. Quartz occurs worldwide; the image alone cannot establish locality or distinguish it confidently from other pale minerals.
