A high iridium content, especially of certain isotopes, indicates non-earthly origin. Please note: this does not necessarily mean that an object was manufactured by aliens. A dagger, belonging to an ancient Egyptian Pharaoh, was found to have an iridium content, indicative of space origin. The iron used to make the blade, had been smeltered from iron ore, taken from a meteorite.
