As of 2020, the most expensive non- synthetic element by both mass and volume is rhodium. It is followed by caesium, iridium and palladium by mass and iridium, gold and platinum by volume. Carbon in the form of diamond can be more expensive than rhodium. Per-kilogram prices of some synthetic radioisotopes range to trillions of dollars.

If the rhodium metal was then left for 20 years after fission, the 13.3 grams of rhodium metal would contain 1.3 kBq of 102 Rh and 500 kBq of 102m Rh. Rhodium has the highest price of these precious metals ($440,000/kg in 2022 [ 3 ] ), but the cost of the separation of the rhodium from the other metals needs to be considered [ editorializing ...
