Likely milky quartz

Quartz (silicon dioxide, SiO₂)

AI-generated identification · may be incorrect

Small, rough, translucent-to-cloudy white/gray fragment with a glassy luster and irregular fracture; quartz has Mohs hardness 7, a trigonal crystal structure, and no cleavage. The photo is not detailed enough to confirm identification.

Physical properties

Formation & geological history

Quartz forms in many settings, including silica-rich igneous and metamorphic rocks and hydrothermal veins; its age depends on the host rock and can range from recent to billions of years old.

Uses & applications

Quartz is used in glass and electronics, while attractive crystals and specimens are collected and sometimes used in jewelry.

Geological facts

Quartz is one of Earth’s most abundant minerals and commonly breaks with curved, shell-like surfaces rather than splitting along flat cleavage planes.

Field identification & locations

Look for hardness (it can scratch glass), lack of cleavage, and a glassy fracture; common worldwide in veins and many rock types. The image alone cannot establish locality or distinguish quartz from similar pale minerals.
