The association offers a wide array of technical and training resources, professional development opportunities, regulatory advocacy, and networking events. Two prominent publications—the Dimension Stone Design Manual and Building Stone Magazine—raise awareness within the natural stone industry and in the design community for best practices and uses of natural stone.
