The diamond industry in India has undergone significant changes over the years. In the early 20th century, India was one of the largest producers of diamonds, with the establishment of the De Beers diamond mines in South Africa. However, after the discovery of diamonds in Russia and Brazil, India's share in the global diamond market declined. In recent years, India has focused on developing its domestic diamond industry, with the establishment of the Gem and Jewellery Export Development Authority (GJEDA) and the Diamond Council of India (DCI). These organisations have helped to promote the Indian diamond industry and attract foreign investment. Today, India is a major player in the global diamond market.
