There's a mineral so rare that only one specimen of it has ever been found in the entire world.

“It’s called kyawthuite (cha-too-ite), a tiny, tawny-hued grain weighing just a third of a gram (1.61 carats). On first glance, you might mistaken it for amber or topaz; but the unassuming mineral speck has value beyond measure.”

    Like the guy who cut down the oldest know tree to find out how old it was. It wasn’t known how old it was at the time. (They have found probably older but don’t want to cut them down to find out.)
