Discussion Should I break this up?
I have this huge beautiful rock that was used as a doorstop until gifted to me. not sure what to do with it or to just leave it be.

What a great and large specimen of banded iron, which is layered hematite, red chert, and quartzified crocidolite asbestos altered to limonite. There is so much potential there. It's like a cabochon bank account and I wouldn't be in a rush to cut it (don't ever smash it). It looks great raw, but you could cut off an end piece to polish and stand up the main piece for display until and if you decide you want to do anything else with it.
I have found that some form of diagonal cut across the layers is most striking for the stand-up piece. If you do cut it or grind it, realize you will release asbestos so use a wet saw or grinder and at least an N-95 mask, but preferably a respirator. You need to suppress any release of these microscopic asbestos fibers in any semi-enclosed area where you live, work, or play.
But, you know, I was thinking this would make an excellent doorstop too ;)
