To do magic. I assume you are only at the beginning of the game because  you will find that once you get to your second boss, either the Eater of Worlds or the Brain of Cthulu or even before that if you manage to find a bunch of gems and craft a staff with them, that it is very usefull to have as much of it as you can. Currently the maximum is 200 mana, so dont make more than 10 crystals, because you cant sell them and otherwise you are just wasting your fallen stars.
