Marble Dining Table - Restore Recommendations?
 

So the wife and I bought a marble dining table when we moved 9 months ago and although it looks pretty dope it's been a nightmare trying to care for it. It has quite a bit of water marks now, and the random really dark mark from us not cleaning up spills quickly, there's also a bit of etching going on. Only talked to one guy so far who says nothing can be done but at the same time it appears all the other companies out there offer service to restore to it's former glory.

Anyone with experience? Recommendations etc?
