It is important to keep in mind that stone is a product of nature and its colors and sizes will vary. All natural stones vary in color, texture and character. The end result of your project will depend on the masonry crew. If every piece has one side of color, but is turned to the inside of the wall, a very different look will be achieved than if the color is managed correctly. A sample panel of the look you desire and a good flow of communication with your mason about the look you wish to achieve are very important.
