Likely milky quartz fragment

Quartz (silicon dioxide, SiO₂)

AI-generated identification · may be incorrect

Small, pale white to translucent fragment with an irregular, possibly conchoidal fracture and vitreous-to-waxy luster. Quartz has Mohs hardness 7, a trigonal crystal structure, no cleavage, and specific gravity about 2.65; these properties cannot be confirmed from the photo alone.

Physical properties

Formation & geological history

Quartz forms in many igneous, metamorphic, and sedimentary settings, including veins from silica-rich fluids; its age depends on the host deposit.

Uses & applications

Common quartz is used in glass, ceramics, electronics, and as a collector specimen; this tiny rough piece has little apparent jewelry value.

Geological facts

Quartz is one of Earth’s most abundant minerals and breaks without forming flat cleavage surfaces.

Field identification & locations

The pale color and irregular fracture are consistent with quartz, but the image is insufficient for a confident identification. A scratch test against glass can help: quartz should scratch it.
