Global Diamond Market Trends

While gem-quality diamonds dominate the global fine jewellery market, the demand for industrial diamonds continues to be driven by a wide variety of sectors including computer chip production, construction, drilling for natural resources, machinery manufacturing, and stone cutting and polishing.

Mining Technology tracks the world diamond market by analysing diamond price trends and the world-wide diamond mine production and reserves. It also monitors the performance of diamond mining companies and major diamond mines around the world to identify the top diamond producing companies and countries.
