Bhopal: A 37.68 carat diamond has been unearthed from Panna mines by the National Mineral Development Corporation (NMDC).

"So far this 37.68 carat is the biggest ever diamond we have recovered from the Panna's Majjhgavan mines," NMDC Assistant General Manager Rajeev Wadhwa said here on Friday.

NMDC'S Mumbai-based valuers will arrive in Panna sometime next month to assess the precious gem, he said.

 However, experts have valued this latest gem somewhere between Rs 2.5 and 5 crore.

Earlier in June 2010, a 34.37 carat diamond was unearthed from the Panna mines.
NMDC began its mining operations in Panna diamond mines in 1968 and since then it has unearthed large number of diamonds from its belly.

The mining operations were stopped from 2005-2009 for want of forest clearance as the mine is situated close to the Panna National Park, which is also a tiger habitat.
