All marble countertops are made from natural stone that has been quarried from mountains all over the world.
As a natural product they are prone to variations in color, pattern and density that actually adds to the beauty and charm of the material. Tiles in stone are under the same management and will also vary from tile to slab material as well as from piece to piece and crate to crate. Marble is fairly soft and functions much better in less used areas. The materials can be scratched if abused and can stain if not cleaned up immediately.
