Granite: a coarse-grained igneous rock composed chiefly of orthoclase and albite feldspars and of quartz, usually with lesser amounts of one or more other minerals, as mica, hornblende, or augite.
Granite sometimes has natural fissures which appear as hairline cracks. These visible hairline cracks are formed during the solidification process. Earthquakes or land movement can also cause fissures. Fissures are not a defect in granite. Many colors have pits which appear like small chips or holes. These characteristics are part of the natural beauty of stone and will not impair the function or durability of the material. As a product of nature it cannot be expected to look manmade.
Obviously this natural rock doesn't come from the earth as it appears in your home. If you've ever wondered how granite is fabricated, watch the process from beginning to end.
