Promethium is a highly radioactive element primarily created in the laboratory, though several of it's isotopes can exist in nature (it's longest-lived isotope has a half-life of only 17 years). It is estimated that in nature, no more than 560 grams (a little over a pound) of Promethium exists in the entire crust of the earth.
