I'm not sure since this project was completed years ago. I will check with the designer and team to see if they remember. And hopefully get back to you with an answer soon.

Hi Julie, I was able to find out the material for you. It is Centurion Stone, Bucks County Cut-Face synthetic stone, blended accents in Fieldstone version of same. The caps are TN grey flagstone 3" thick. Hope this helps as you plan your project!
