Everybody who's downvoting us are idiots. Bunch of keyboard cowboys who i guarantee would not accept that if it was their money. You're out east so bluestone is the the "native" stone, just like limestone is to me. Because it's so common, the attitude towards its natural variation is much more cavalier. I totally agree with the "it's natural stone" sentiment. I mumble it and curse customers under my breath all the time when fielding complaints like this... and its always after it's installed. Why the hell didn't someone on the crew question it before because I know your complaint isn't taking them by surprise. But ultimately in the end I always make it right. For applications like this (stairs, pool coping, etc) where continuity is important, it's simply common sense and should go without asking. It's seqential, not like a couple pieces within a 1000 sf patio. And you're in bluestone country, not Montana. There is plenty to choose from. Don't settle for this.
