The Natural Diamond Council operates as an industry authority and resource on natural diamonds for both consumers and the jewelry sector. Its work centers on communicating the value of natural diamonds and the companies that supply them, promoting ethical, social, and environmental standards, and ensuring clear, accurate information about the diamond trade. The council includes five member companies that together account for roughly three-quarters of the world's rough diamond production, with operations spanning six continents and many countries. It also supports consumer education through its Only Natural Diamonds brand and digital publishing platform. Headquartered in New York, New York, the organization serves a global market in the luxury jewelry space by promoting transparency and trust and by offering education to consumers and trade through resources such as the Diamond Learning Center. In 2026 it announced World Diamond Day, a worldwide initiative intended to recognize natural diamonds and the shared community around them.
