About Us

Custom Fabrication

Founded in 1991, Natural Stone Designs both fabricates and installs natural and engineered stone products. Because we do our fabrication in-house, you can be assured of excellent work and careful quality control. In fact, Natural Stone Designs is accredited by the Marble Institute of America, a rigorous process that guarantees you are working with a safe, competent, and ethical company.

As part of Columbia Stone, we import our own stone from all over the world and maintain an extensive inventory, allowing us to cut out the middleman and pass the savings along to you.
