Diamonds were discovered in India by the 4th century BCE. In addition to the diamond legends, India yielded many legendary diamonds, including the Koh-i-Noor, the Orlov, the Hope, and the Sancy. Except for a minor supply of diamonds from the Kalamantian deposits of Borneo, dating from the 6th century CE, India was the world's only source until the 1730s. Most of India's deposits were alluvial, but today the Majhgawan pipe, a primary source near Panna, is the country's only producing diamond source.
