This is a hand select (not palletized) 2" thick pennsylvania bluestone

Hi, thank you very much for your quick response. Is pennsylvania bluestone a type of slate? Do you know if it is available in Canada? What do you mean by hand select? Also, is this patio on a concrete base? I was wondering why you used such thick stone? We are planning a 900 square foot patio on a concrete base and we were told that 3/4 inch would be thick enough. Thanks!

I used a stone for my patio that looked very similar called Arkansas Blue
