Oil Stone isn't found naturally in the game, yet. Its only use is in making Polymer which you can get from Astronaut lairs. If you really really want Oil Stone see the alchemy section on the Brown Mob page. If you are asking about Pink Crystal, it can be found 'growing' for the ground often with other Plants. It's a little bit hard to spot because it is almost transparent, it's also fairly rare.
