As a product of nature, variations in color, mineral deposit, fissures and pits are commonly seen in stone products. These occurrences are not flaws; they are the result of the stone's geological formation and are part of the natural beauty and character that comes with using natural material. Variations in color and thickness are common and may even occur in the same slab, resulting in tops not to match exactly in color or grain. Samples used as a representation of the final product will also not be an exact match. Natural stone and quartz products will have visible seams. Seams are placed according to material size and other limitations. Concerns about seam placement should be addressed at the time of measure.
