Campo de Cielo Meteorite Sterling Silver Ring Size 6

Campo de Cielo meteorite gemstone set on a sterling silver ring, size 6.  Campo de Cielo meteorites are iron and nickel meteorites found in northern Argentina.  The meteorite craters were reported in 1576, but were already well known to the aboriginal inhabitants of the area.  The Natives claimed that the mass had fallen from the sky in a place they called Piguem Nonralta, which the Spanish translated as Campo del Cielo, which translates to "Field of Heaven."  An expedition led by Rubin de Celis in 1783 used explosives to clear the ground around the craters and found that it was probably a single stone. Celis abandoned it as worthless. He did not believe that the stone had fallen from the sky and assumed that it had formed by a volcanic eruption. However, he sent the samples to the Royal Society of London. Those samples were later analyzed and found to contain 90% iron and 10% nickel and assigned to a meteoritic origin.
