The SDB is a “one-stop destination” for over 65,000 diamond professionals, including cutters, polishers and traders. It is expected to save thousands of people from travelling to Mumbai by train to do business.

The building was designed by Indian architecture firm Morphogenesis following an international design competition. It was completed in four years and was officially inaugurated by Prime Minister Narendra Modi in November 2023.
