2018 Investors

The money raised through business and individual donation has enabled the NSC to make significant progress in their branding campaign for Genuine Stone™ as well as supporting the Sustainability Committee on benchmarking studies, industry awareness initiatives and development of a natural dimension stone standard. These efforts would be non-existent without the financial support of donors.
