Limestone is one of the most popular and usable dimension stones available. Limestone has a uniform texture and grade that weathers naturally over time, gaining a natural patina and improving in appearance over time. While subtle color and grain variations are present within a deposit, limestone is actually very homogeneous for a natural product.

· Properties of Limestone: Calcium Carbonate Content: Limestone is primarily composed of calcium carbonate (CaCO3), which gives it its fundamental chemical composition. Color: Limestone can vary in color, from white and gray to yellow, brown, and even black. The color often depends on impurities and mineral content.
