Lime Stone Limestone is a sedimentary stone mainly consisting of Calcite.Limestone has a very fine grained surface texture, does not show much crystalline structure and varies in hardness.Limestone is a hard, impervious and compact rock with very low water absorption, and has a high resistance in freezing and thawing conditions, hence can be used in any atmospheric condition without getting affected. Some dense limestones can be polished. The common colors are blue, grey, black, brown, and green.
