The campo del cielo meteorite is an iron meteorite discovered in the eponymous region located in northern Argentina, on the border between the provinces of Chaco and Santiago del Estero. This area, whose name means "field of the sky", owes its designation to a meteorite shower that occurred approximately 4,000 to 5,000 years ago. The strewn field, which extends over several kilometres, has yielded numerous fragments since its official discovery in the 16th century, although the indigenous populations had known of its existence well before then. Composed mainly of iron and nickel, this meteorite belongs to the octahedrite class, characterised by a distinctive crystalline structure visible after chemical etching of its surface.

The mini campo del cielo meteorites offered in this collection are authentic fragments from this world-renowned archaeological and scientific site. The reddish-brown to greyish colour of the surface results from the natural oxidation of iron on contact with air and moisture over the millennia. These small specimens provide an accessible introduction to meteoritics for beginner collectors as well as for Earth science enthusiasts wishing to add to their collection. Their compact size allows for easy handling whilst retaining the physical characteristics typical of iron meteorites.

These fragments, several thousand years old, bear witness to a major cosmic event that shaped the geological history of the region. They provide an interesting educational tool for understanding the composition of metallic meteorites and the formation processes of the solar system. Ideal for a personal collection, educational use or a cabinet of curiosities, these pieces are suited to anyone interested in mineralogy and the natural sciences. Available in several sizes and weights, they allow for a varied collection to be built whilst remaining true to the geological authenticity of this exceptional site in Argentina.
