Yes, granite being crystalline in structure always has tiny pits – spaces between the various mineral crystals. Some granites pit more than others when being polished, we suggest that you take a closer look at the slab you choose for your job. Chances are, if you look at it across the light you will notice the natural pitting of that stone. Remember, this is natural and it should not be considered an imperfection of the stone. 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.
