Iron meteorite from Campo del Cielo, Argentina – pendant in 925 sterling silver

An iron meteorite pendant from Campo del Cielo, Argentina, set in 925 sterling silver. The piece carries 4.5 billion-year-old material directly on the neck, one of the oldest solid materials in the solar system.

Campo del Cielo, the strewn field in the Argentine Chaco region, documents one of the largest meteorite impacts in recent Earth history approximately 4000 years ago. Indigenous populations knew about the iron masses long before documented European finds in the 17th century.

The iron-nickel alloy with characteristic kamacite-taenite lamellae creates the famous Widmanstätten patterns. These geometric patterns can only form through extremely slow cooling in the asteroid core. The estimated cooling rate is one degree per million years.

The hand-set sterling silver mounting follows classic European jewelry tradition. It protects the iron material from direct skin contact, as iron meteorites can oxidize when exposed to sweat.
