Likely milky quartz fragment
Quartz (silicon dioxide, SiO₂)
AI-generated identification · may be incorrectSmall, pale gray-white, translucent to opaque fragment with a vitreous-looking surface. Quartz has Mohs hardness 7, a hexagonal crystal structure, no cleavage, and uneven to conchoidal fracture; the photo does not show enough detail to confirm these tests.

Physical properties
Small, pale gray-white, translucent to opaque fragment with a vitreous-looking surface. Quartz has Mohs hardness 7, a hexagonal crystal structure, no cleavage, and uneven to conchoidal fracture; the photo does not show enough detail to confirm these tests.
Formation & geological history
Quartz commonly crystallizes from silica-rich fluids in veins and igneous or metamorphic rocks; its age depends on the host deposit and cannot be inferred from this fragment. Quartz veins and quartz-bearing rocks are geologically plausible in Ethiopia, including the broad region near the reported coordinates.
Uses & applications
Quartz is used in glass, ceramics, electronics, and as a gemstone or collectible; this small unworked piece has little practical value.
Geological facts
Milky color usually results from tiny fluid or gas inclusions scattering light. A steel nail should not readily scratch quartz, while quartz can scratch glass.
Field identification & locations
The specimen is consistent with common vein quartz, but the blurred image cannot rule out another pale mineral. Check for glass-scratching hardness and absence of cleavage; precise identification may require a close-up or simple tests.
