It doesn't look like petosky stone from here as far as the matrix goes but the floweretts do. If it is petosky, it could be quite vaulable. Sure would like to see a slab of it though

Maybe try to polish a small window, showing the cell structure. Is that one an agate replacement, or a softer material ?If it's agate, it would cut some beautiful cabs. But due to its size, may be worth more a specimen. Don

I hate to say it, but it looks like limestone to me. I left a piece that size behind on a trip to Montana last weekend. A fun specimen to have, but probably not worth much.
Yes, a Dremel would work.

That is a really cool piece!! I have some smaller ones that are in the form of sandy chert and limestone. A piece this size is increadible! I know this might sound like cheating, but, if it is a softer material like you think it is you could possibly try some kind of sealer like Tompsons Water seal (like you would put on your foundation or deck) or a clear, water-based wood finish. It will bring out the pattern and preserve it and really highlights the cell structures - I have done this with petoskey stone slabs that wont hand polish, and they look great for display pieces.
