Formed over the centuries in only one place on earth — the Cumberland Plateau — Crab Orchard stone is an especially hard, weather resistant variety of sandstone due to unusually high concentrations of silica. The stone’s exclusive buff, tan, blue-gray and pink colors were created by a mixture of iron, titanium and magnesium. And the yellow and brown swirls that give the stone its one-of-a-kind appearance come from iron stains and natural weathering.
