The Natural Stone Institute is a trade association representing every aspect of the natural stone industry. The current membership exceeds 2,000 members in over 50 countries. 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. The association serves as the authoritative source for safety and technical standards and information regarding the use of natural stone. It operates an industry accreditation program and two prestigious awards programs, as well as a continuing education program for architects and designers. The Natural Stone Institute was formed in 2018 as a merger of the Marble Institute of America and the Building Stone Institute. The Building Stone Institute was formed in 1894 as the International Cut Stone Contractors and Quarrymen’s Association; the name was changed to the Building Stone Institute in 1955. Established in 1903 as the National Association of Marble Dealers, the Marble Institute of America officially formed in 1944, when the association merged with the National Association of Marble Producers. In 1962, the National Association of Marble Builders merged with MIA. In 2021, the National Building Granite Quarriers Association (NBGQA) merged with the Natural Stone Institute. The NBGQA was founded in 1916.

Founded in 2002, we’re a family company with an entrepreneurial spirit to find innovative solutions to help customers protect what’s most important to them, from the delicate surfaces in their homes to avoiding costly repair or replacement to protecting their families and homes against harmful germs. It started with a passion to make natural stone and quartz care and maintenance easy for homeowners with the best solutions and technologies drawn from a family legacy. The Granite Gold® brand was born out of three generations’ expertise in stone and quartz fabrication, installation and restoration. Our founders, cousins Lenny Sciarrino and Lenny Pellegrino, grew up in the family business and are named after their grandfather, Leonardo Pellegrino, who came to the United States in the 1950s, bringing with him an Italian heritage known for expertise in the stone industry that he passed on to generations of family. The same passion to bring innovation to customers led us to introduce the MicroGold® brand of powerful antimicrobial and antibacterial solutions to help customers protect their families and homes. With Guardsman®, it’s more than a century’s worth of expertise in caring for and protecting wood furniture – trusted worldwide by furniture professionals – and our industry-leading formulas also include care and maintenance for fabric, leather, appliances and outdoor furniture. Passion. Innovation. Expertise. Our commitment to our customers.
