The shelves are quarried slate that we selected and cut into the fire wall.

Is this the color they call "Rust Multi Slate" in the ledger stone style tiles?

Where did you get the stone shelves from is it the same place as the stone veneer. Thank You

Thanks for the question! We went to a local quarry and sourced flagstone for the shelves, it was relatively easy to find stone that blended with the wall cladding.
