Quartzite is a metamorphic rock that is naturally formed from sandy quartz particles and a binder under high pressure and heat. Because of its high quartz content, this natural stone is particularly hard and also acid-resistant and relatively insensitive to scratches. Both the front and the edges themselves are finished with natural stone. Granite is a primary or deep rock that was formed when the earth's crust cooled down about 500 to 800 million years ago. When handled and cared for correctly, granite is characterised by its hardness and is also insensitive to scratches, acid-resistant, heat-resistant, particularly hygienic and easy to clean. Both the front and the edges themselves are finished with natural stone.
