I'm a little surprised there isn't a giant k-way tie for minerals that have only been found once. Like, I get that minerals arise from natural processes, and it's a big planet, so maybe every process should have a potential to occur more than once and perhaps in more than one place -- but many kinds of natural processes create a long-tail distribution where there's a huge number of very rare things.
