The most expensive element in the world is Francium.
The most expensive element on the planet is Francium. This element is naturally present. But it is very difficult to get it in its original state. Its half-life is very short and it decays very quickly. So far, only a few atoms have been preserved in their original state.
It is so expensive that if you want to get just one gram of Francium you have to pay 1 billion US dollars for it.
