Small metallic-looking mineral/rock fragment

Indeterminate from image; possible pyrite-bearing sulfide rock or native-metal/meteorite fragment

AI-generated identification · may be incorrect

Granular, dark brassy-brown surface with metallic to dull luster; apparent grain size is a few millimeters. Hardness, cleavage, crystal structure, and specific gravity cannot be reliably determined visually; pyrite would be Mohs 6–6.5, while many meteorites are typically 6–7.

AI Estimated Value

Unidentified fragment: usually under $5; common pyrite: $1–$20; a confirmed, authenticated meteorite fragment could range from roughly $50 to several hundred dollars depending on type and provenance.

Physical properties

Formation & geological history

Could be a natural sulfide mineral fragment, weathered ore, or possibly a tiny meteorite, but the photograph lacks diagnostic evidence. A geological age and formation environment require testing and examination of a fresh surface.

Uses & applications

Likely a curiosity or specimen fragment; pyrite-bearing material may be collected or used as an ore, while confirmed meteorites can have collector value. It is unsuitable for construction or jewelry without identification and preparation.

Geological facts

The brassy color may suggest pyrite (“fool’s gold”), but its irregular granular form is not diagnostic. Magnetism, streak, density, and microscopy are useful for distinguishing pyrite from meteorite material.

Field identification & locations

Check whether it attracts a strong magnet, leaves a dark greenish-black streak on unglazed porcelain, and has unusually high density; do not scratch valuable surfaces. A fresh broken face and professional testing are needed for reliable identification.
