But no country in the ancient world adored carnelian as much as India, which mined, processed, used and exported this gem mineral for three to four millennia since the Pre-Harappan era. India has ever been famous for the quarries of carnelian and agate (from which carnelian is made by simple heating) situated (a) in the neighbourhood of Ratanpur, on the lower Narmadā river, in the (former) state of Rājapipla, (b) in the country north of Rājkot, in the Kāthiāwār peninsula, and (c) in the Rājamahal hills in the east where the Ganges bands. The lapidaries in Broach, Cambay, and Jabalpur, using materials of the above areas, such as carnelian, agate, moss-agate, heliotrope or blood-stone, have been world-famous.
