Jerry: Where does the rough come from?

Rosh: Rough material comes from places around Jalna and Aurangabad in Maharashtra state, where the famous Ajanta and Ellora caves are located, from Jagadia in Gujrat state, from Hyderabad region (where Golconda mines and Fort is located and Kohinoor was mined here) and also Kangyam and Karur region in Tamil Nadu state.
