Natural Stone Institute

On January 1, 2018, the memberships of the Marble Institute of America (MIA) and the Building Stone Institute (BSI) voted to officially authorize a merger. The organization is now known as the Natural Stone Institute. We serve more than 1900 members in 55 countries who represent every aspect of the natural stone industry, offering them a wide array of technical and training resources, professional development, regulatory advocacy, and networking events. Two prominent publications - the Dimension Stone Design Manual and Building Stone Magazine - raise awareness in both the industry and the design communities for the promotion and best use of natural stone. The BSI incorporated in 1919. MIA traces its roots back to the National Association of Marble Dealers, founded in 1907, which joined with the National Association of Marble Producers in 1944 to form the Marble Institute of America (MIA). The National Association of Marble Builders merged with MIA in 1962.
