Don't care much for the chipped edges. Could be that there weren't enough "good" tile for them to use, or that they were just to lazy to cull the bad ones.

It's difficult to tell from the closeup pics, but it appears that there may be some significant lippage on some of those. That's certainly not acceptable.

I agree about the lippage - might explain the chips too, if other trades were in the house before the stone was grouted. Still, the installer should fix the issue.
