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.

Limestone Fact Sheet – Natural Stone Council

Limestone: A sedimentary rock consisting primarily of calcium carbonate, often in the form of the minerals calcite or aragonite, and sometimes with magnesium carbonate in the form of dolomite. Minor amounts of silica, feldspar, pyrite, and clay may also be present. Limestone can occur in many colors but is usually white, gray, or black.
