Limestone is a sedimentary rock composed primarily of calcium carbonate. Depending on the formation process limestone can be classified as an organic or chemical sedimentary rock.

Organic limestone, also called biological limestone, forms in shallow, warm marine waters from the accumulation and lithification of shells, corals and skeletal debris of sea creatures. The German Jura Beige and the English Mandale Derbyshire are great examples of sedimentary organic limestone rich in clearly distinguishable fossils.

Limestone can also form through evaporation of ground or surface water rich in calcium minerals. Direct precipitation of calcium carbonate result chemical sedimentary rocks, such as travertine and tufa.

Pure limestone is white in colour but due natural impurities it is often cream, brown, grey, blue and black in colour.

Limestone is one of the most porous natural stones. This high porosity makes it more susceptible to absorption of oils, dirt and grime than other natural stones.

We have compiled a online sample gallery to give our clients an idea of the available limestone colours. The sample gallery is not exhaustive. If you are unable to find the limestone material that you are looking for, please do not hesitate to contact us. We have a dedicated team who can assist you in sourcing and finding the right stone for your project, or, offer alternatives if needed.

Please note these images are put in place to give an idea of the available and known limestone materials. Misconceptions sometimes occur because of the following reasons:

  • Limestone is a natural stone therefore its colour may vary from batch to batch

  • Samples represent just a small area of an actual limestone slab/block

  • We encourage all our customers to view the selected limestone material in person whenever is possible

  • Slab and sample images are representational only. Due to changes in lighting conditions limestone slab and sample may appear different in pictures than it does in real life

  • The displays of smart devices, tablets and personal computers sometimes interpret colours differently
