In 2016, the Marble Institute of America (MIA) and the Building Stone Institute (BSI) established a collaboration. BSI was providing its members with educational material empowering them to provide products and services of the highest quality by informing them about the design of natural stones. MIA, on the other hand, aimed to increase the use of natural stone by setting standards for the use of natural stone, creating user guides on this subject, and educating manufacturers, end-users and architectural companies around the world. In 2018, the Natural Stone Institute (NSI) was born from the partnership of these two trade associations. The aim here was to bring together the leading names of the sector, which currently continues their commercial activities, under a common roof, to share their experiences and to increase the use of natural stone all over the world in a qualified way. The Natural Stone Institute, which is a commercial association with more than 2000 members from 55 countries around the world, has created a user guide that represents every aspect of the natural stone industry, from the manufacturer to the end-user. In addition, the NSI has started a serious movement towards the use of natural stone in the modern world with the programs it has developed, its resource archive, its trainings and its campaigns.
