Indiana Buff Limestone
Indiana Limestone is one of the most widely-used, natural stones in the world. It is neutral in color and almost without blemish. The color range is a warm white (or buff) tone. This limestone has no discernable grain structure, giving it equal physical strength in all directions. Combined with a high resistance to deterioration from weather and pollution, this stone is a great choice for any application where natural stone and crisp detail edges are desired.
