Physical properties
White to translucent, vitreous luster, irregular fracture, and no obvious cleavage; Mohs hardness 7. The small, rough fragment appears quartz-rich, though the photo does not show enough detail for confident identification.
Formation & geological history
Quartz forms in many settings, including cooling silica-rich magma and mineral-filled fractures; its age and specific origin cannot be determined from the image.
Uses & applications
Quartz is widely used in glassmaking, electronics, construction aggregate, and decorative objects; this fragment appears mainly suitable for a collection or craft use.
Geological facts
Quartz is one of Earth’s most abundant minerals and commonly breaks with curved, shell-like fracture surfaces.
Field identification & locations
Look for glassy surfaces, hardness sufficient to scratch ordinary glass, and absence of cleavage. Quartz occurs worldwide in veins, pegmatites, and many rocks.
