All the manuals listed eight sources of diamond, but as Finot suggested, several of these were trading places and not actual mining areas. The bank of the Veṇā (Wainganga near Nagpur) had diamond mines; the place seems to be Wairagadh formerly known as Vajragṛha. This place, the area of Vidarbha, had been mentioned by Kauṭilya as Sabhārāṣṭra. Kosala or South Kosala meant the Bundelkhand area around Pannā; the diamond field of this area tempted many invaders such as the Kuṣāṇa King, Kaniṣka. Mataṅga is the tract between Kṛṣṇā and Godāvarī, including the area of the Golconda mines. Kaliṅga included the Mahānadī alluvium in the Sambhalpur district of Orissa. (Shastri, 1969:325-27)
