This unbelievable piece comes straight from outer space. Five-thousand years ago the giant "Campo del Cielo" meteorites bombarded what is now Chaco Province in Argentina. In 1576 Spanish explorers discovered the massive craters and monstrous iron meteorites weighing several tonnes, along with many small fragments.

Small measures approximately 1 x 1.25 inches (2.5 x 3.25 cm). Weighs approximately 16 to 20 grams.

Large measures approximately 1.5 to 1.75 inches (3.7 to 4.5 cm). Weighs approximately 80 to 90 grams.

The composition is primarily iron with traces of Nickel and Cobalt.
