Marble products may have small amounts of colour-matched filler to give the impression of a continuous surface. The nature of marble is such that when it is formed in the earth, some small cracks are created too. To achieve a perfect piece of marble with no imperfections at all means a huge amount of wastage. This has two principal effects, the product becomes prohibitively expensive and the natural resources are depleted too quickly - a much more harmful approach to the world's environment.
