Cutting granite rocks for fish tank.

[bitterman]

I have a LARGE egg shaped piece of granite (about 25-50 lbs?? 10" diameter 14-16" long?) that I want to cut the bottom off so I can stand it up in my tank. I removed it from my tank since it shifted off the rock it was sitting on to lean a little against the back glass of my tank (This could have been bad)

Any suggestions on how to cut it? Can anyone help me out? Diamond Wet saw anyone?

Thanks,
