This metamorphic stone is well known for its use in famous buildings and sculpture around the world. It comes in a variety of colors and patterns, depending on where it’s quarried. Because it’s made of metamorphic limestone, marble is very porous in nature. For this reason, it can be susceptible to staining if not treated and sealed regularly. For the same reasons, it can also etch from coming into contact with acidic foods or liquids. Marble is a much more high-maintenance stone than others, for this reason, we don’t recommend using it in high traffic/high use areas like a kitchen. Marble ranks a 3-4 on the Mohs Scale of Hardness.
