This is a Full range Bluestone with a natural cleft finish (1" thick on
mortar, 4" of concrete and compacted base rock) . The pattern is custom
and the color is specified for this project without rusts or lilacs.
There is a finished (gauged/flamed) edge on the steps. The step treads are what they call 'select blue' which means they are hand selected (and specified) for the amount of true color.

Let us know if we can be of any assistance with your project or if you have additional questions.

Good luck and happy 'Houzzing!'

Thanks,
TLC
