Unfortunately, we don't recall the exact brand of stone on this wall. There are several natural ledger stone suppliers on the market with similar products. Also, see this link for a similar man made product that looks fantastic. It's called El Dorado Stone: http://www.eldoradostone.com/products/stone/nationwide-profiles/stacked-stone/#/nantucket/
