Since 1919, the Building Stone Institute has worked on behalf of the quarries, fabricators, retailers, importers, exporters, carvers, sculptors, restorers, designers, and installers that comprise our diverse membership. BSI provides programs and services that empower our member companies to offer the highest level of quality products and services. BSI resources are necessary tools that enable our members to educate the architectural and design communities on the benefits and uses of natural stone. BSI is a not-for-profit trade association dedicated to serving its member firms, and providing educational materials and continuing education on the uses and benefits of natural stone. We support efforts to continually increase the quality of service, quality of products, and demand for stone. Our website provides information about the organization, an abundance of stone awareness and technical guidance, plus a convenient resource to locate experts and all aspects of natural stone. BSI is a proud continuing education provider with the American Institute of Architects and the American Society of Landscape Architects; is a founding member of the Natural Stone Council and a member of the U.S. Green Building Council.
