Granite, which is crystalline in structure, always has tiny pits – spaces between the various mineral crystals. Different minerals that make up the stone reflect light differently. Some spots can look shinier than others. Granite sometimes has natural fissures as well, which may look like cracks, but are not structural defects and are a naturally occurring result of the immense heat and pressure which formed the granite eons ago. These characteristics are part of the natural beauty of stone and will not impair the function or durability of the material. A product of nature cannot be expected to look manmade.
