Likely native silver-bearing ore or metallic slag-like specimen
Uncertain from the photograph; possible native silver (Ag), but identification requires testing
AI-generated identification · may be incorrectRough, irregular, dark metallic-gray surface with bright reflective patches; hardness, streak, crystal structure, and specific gravity cannot be determined visually. Native silver is Mohs 2.5–3, metallic, and malleable; this specimen’s appearance alone is not diagnostic.
