Pseudometeorite ironstone or weathered metallic nodule

Uncertain; likely iron-oxide-rich limonite/goethite with magnetite or hematite

AI-generated identification · may be incorrect

Dark brown to black, smoothly weathered, submetallic to dull luster, irregular vesicular-looking cavities, and moderate-to-high density. Likely hardness about 5–6.5 Mohs; composition and magnetism require testing, so it cannot be reliably identified from the photograph alone.

AI Estimated Value

About $1–$15 as an unverified common nodule; a professionally authenticated meteorite, if applicable, could be worth substantially more.

Physical properties

Formation & geological history

Probably a terrestrial iron-rich concretion or weathered ironstone formed by groundwater alteration and oxidation, commonly in soils, stream gravels, or sedimentary environments. The image does not establish a meteorite origin.

Uses & applications

Primarily a curiosity or teaching specimen; ironstone may be collected, and iron ores have industrial value, but this small piece has no practical construction or jewelry use.

Geological facts

A smooth dark surface and pits are not diagnostic of a meteorite; terrestrial ironstone commonly resembles meteorites. A strong magnet response, streak, density, and nickel test would help distinguish possibilities.

Field identification & locations

Check for a dense feel, magnetic attraction, and a brown-red streak on unglazed ceramic; meteorites generally lack a red streak and show a thin fusion crust, while ironstone often stains reddish-brown. Common analogs occur worldwide in weathered iron-rich terrains.
