coltonscustoms06@msn.com i will be glad to help as for sand it also depends on the size of your rock aluminum oxide cuts the fastest but is also the most expensive if your product is small enough you can use a sandblasting cabinet wich can be picked up at a place such as harbor frieght for pretty resonable if it is too large i would suggest using black magic or black beauty it will use alot of sand so be prepared garnit also works good if you can find it most sign companys will have the sandblast mask material if not any headstone shop uses it if you wish not to try it most headstone shops will engrave it for you ( for a fee of course) you can aslo use a laser but it will only etch the surface like i said feel free to email me i will be glad to help also my website is
