Iron meteorite from Campo del Cielo, Argentina

A loose iron meteorite fragment from Campo del Cielo, Argentina. The piece has an unusually high weight-to-volume ratio, a direct haptic authenticity marker.

The material density of iron meteorites (7.8-7.9 g/cm³) is 2.5-3× higher than most terrestrial rocks. When lifting the piece, the high density is immediately noticeable, a characteristic that no synthetic material can replicate without the use of iron or heavier metals.

Collectors routinely use this density test as a first authenticity check, supplemented by a magnet test (iron meteorites are strongly ferromagnetic) and visual inspection for Widmanstätten patterns on polished cut surfaces.

The loose format without a setting makes all these tests directly accessible. Collectors can fully examine the piece haptically and visually.
