My fluorite got pwnd

I did my little divination class for Harry Potter night, and brought some crystals along. Unfortunately, I included a chuck of pointy fool's gold, and a few of the others have gouges and scrapes on them now. The fluorite especially, it has lots of little holes in it.
Any suggestions for getting it back to being smooth? Would I have to put it in a tumbler?

i don't think it really matters in regards to the properties if it has scrapes?
but if it's annoying that they're like that (and i know how that feels) i think you would need to use a tumbler
