Limestone

In geological terms, a limestone is a sedimentary rock consisting mostly of calcium carbonate, usually in the form of the mineral calcate. Limestone may be formed in a variety of ways, but many are highly fossiliferous and clearly represent ancient shell banks or coral reefs. Many examples of limestone may be hundreds of millions of years old, and can give a fascinating indication of general reef conditions at the time of the formation. A detailed study of ancient reef limestone will show many species of shell and coral which became extinct on earth millions of years ago. Because of their environment of formation, most limestone will show a naturally high degree of variation, in terms of colour, fossil content, mineral grains, etc. Like all rock types, limestones have often been subjected to natural earth stresses, resulting in features like jointing, which are sometimes filled  by later veins of minerals like quartz and calcite. As with the original variations of colour and mineral texture, described above, these joints and veins are totally natural features, and indicate the history of formation of the limestone.

Limestone is a natural material, and as such, is inherently variable in shade and colour. No guarantee can be given that the product will be uniform, or indeed the same colour as depicted in the showroom or samples.
