What happens to rough diamonds?

Most rough diamonds are used for industrial purposes. Approximately 46 percent of the world’s rough diamonds were produced for the industry and 19 percent were produced into gem-quality polished stones. The value of diamonds increases almost exponentially as it travels from the mine to the final endpoint or market. Demand for diamonds is primarily driven by the United States, India, and China. However, demand from the United States dropped below that of India and China in 2020.
