Limestone: Limestone is lauded for its aesthetic diversity and flexibility. In color, limestone ranges from pure whites, beiges, to subtle browns with hints of blue. In texture, limestone ranges from creamy and soft to chunky and harshly veined. Limestone is a great option for building faces because it can be carved and shaped relatively easily.

How Strong Is Limestone? Although relatively soft with a Mohs hardness of 2 to 4 dense limestone can have a crushing strength of up to 180 MPa. For comparison concrete typically has a crushing strength of about 40 MPa. Although limestones show little variability in mineral composition they show great diversity in texture.
