A. No way. Marble, granite and limestone are natural materials that are quarried from the earth. They are fabricated into tiles or slabs in factories but they are totally natural. Stones are comprised of different minerals that formed together millions of years ago. Veining, holes and fissures should be there and occurred naturally in the formation. With some stones, factories do use filler and resins to make the stone a workable material for tiles and slabs. Stones that show heavy color variation and a movement effect in the veining may well contain more fissures and less uniformity in pattern. This is simply part of the unique beauty of nature and a desirable characteristic.
