London Valley: Brown is the new grey, so we are told. London Valley is made from blocks that make up both Brown in our wilderness collection, and the London Panels in the Stone Panels collection. These blocks produce a variety of brown, cream, to nearly black with hints of brown products. This product comes in 4 heights that work together to make it easier for stone masons to make more modern linear patterns of this product. (2 1/4″, 5″, 7 3/4″, 10 1/2″)
