Unidentified dark metallic fragment

Possibly iron-rich mineral or metallic meteorite fragment; image is insufficient for a reliable identification

AI-generated identification · may be incorrect

Small gray-brown, reflective, irregular fragment with apparent metallic luster; hardness, crystal structure, cleavage, and specific gravity cannot be determined visually. The bright surface may also be a polished or tarnished mineral grain.

AI Estimated Value

Typically under $5 if an ordinary mineral fragment; approximately $20-$200+ if authenticated as a small meteorite, depending on rarity and provenance.

Physical properties

Formation & geological history

Could derive from an iron-bearing terrestrial mineral, slag-like geological material, or meteorite; no geological age or formation environment can be established from the photograph.

Uses & applications

Uncut material has little industrial or jewelry use unless testing confirms a valuable mineral or meteorite; verified meteorite specimens may have collector interest.

Geological facts

A magnet test, streak test, density measurement, and examination for fusion crust or chondrules would help distinguish an iron mineral from meteorite material.

Field identification & locations

Test whether it is magnetic, inspect with a loupe for a thin dark fusion crust, and measure density; avoid destructive testing before professional examination. Common iron minerals include magnetite and hematite, while meteorites are found worldwide but are uncommon.
