B. What are the different kinds of natural stone and where do they come from?
Limestone is a sedimentary rock mostly composed of fragments of marine organisms. Colours can range from black and blue through to grey, beige and cream. Our limestone tiles come from countries including Portugal, France, Morocco, Vietnam, India and China.
Marble results from the metamorphism of sedimentary rocks which creates an interlocking mosaic of carbonate crystals. Pure white marble is the result of a very pure limestone. The characteristic veining found in many marble tiles is created by the presence of impurities such as clay, silt, sand or iron. Our marble tiles are sourced from countries including Italy, Spain and China.
Slate is a fine-grained metamorphic rock derived from a shale-type material composed of clay or volcanic ash. Colours vary from black and grey through to purple and green-grey. Our slate range includes tiles from Brazil and Argentina.
Basalt is a dark, fine-grained igneous rock which commonly forms from the rapid cooling of lava flow and is extremely dense, making it a very durable stone. The basalt tiles featured in our collection are from Italy, Vietnam and China.
Sandstone, including England’s popular York stone, is a sedimentary rock composed mainly of sand-sized minerals and rock grains, most commonly quartz, which have been compacted together. Colours can range from warm beige through to cooler grey. Our sandstone products are sourced from the UK and also India.
