The Panna diamond mines, known as the Panna group, are a large group of diamond deposits in the Vindhya Range in West-Central India, covering approximately 20 acres of land. No large diamonds have come from this area.
The diamond mines in Panna are managed by the National Mineral Development Corporation (NMDC Ltd.) of the Government of India. All diamonds are collected by the district magistrate and are auctioned in the month of January. All auctions are open to the public and usually offer more than 100 diamonds.
According to NMDC’s website, the Panna diamond mines have a capacity of 84,000 carats per year. More than 1 million in carats have been recovered as of 2012.
