Likely polished dark stone or mineral specimen (unidentifiable from image)
Undetermined; possibly dark quartz-rich material, basalt, or obsidian
AI-generated identification · may be incorrectThe image is extremely dark and partly obscured, but the object appears smooth, rounded, and weakly reflective with a warm orange-brown illuminated area. Hardness, cleavage, crystal structure, and specific gravity cannot be determined visually.

Physical properties
The image is extremely dark and partly obscured, but the object appears smooth, rounded, and weakly reflective with a warm orange-brown illuminated area. Hardness, cleavage, crystal structure, and specific gravity cannot be determined visually.
Formation & geological history
Formation and geological age cannot be established without clearer views or testing. The reported Ethiopian region near 9.6°N, 41.8°E contains volcanic and metamorphic rocks, so basaltic or quartz-bearing material is plausible.
Uses & applications
If stone, possible uses include ornamentation, collecting, or jewelry; no specific industrial use can be assigned from this photograph.
Geological facts
The bright white edge may be reflected light rather than a crystal face or fracture. It could also be a non-geological object or a polished specimen, so identification confidence is very low.
Field identification & locations
Photograph it in daylight against a plain background, including multiple angles and a scale. Useful tests are streak, hardness, magnetism, translucency, and acid reaction; do not scratch valuable material. Regional possibilities include basalt, quartz, jasper, or metamorphic rock.
