Diamonds have been attracting the people and the kings alike since centuries. Still today, diamond is considered as the mark of one’s prosperity. It is the hardest substance found in nature. India was the only source of diamonds in the world for over 3000 years till diamond was extracted in Brazil and South Africa. At present there are only around 50 active diamond mines in the world. The diamond mines are usually located in very remote, and often very harsh environments.
Diamonds are a crystallised form of carbon that grows from a primary carbon source when subjected to very high temperatures and pressure in an area of the earth’s mantle about 150 km below the surface. This area is often known as the diamond stability zone, where temperatures are above 1000 degrees Celsius. There is also tremendous pressure at these depths. In nature, this process can take anywhere from one billion to over three billion years.
Once diamonds are formed in the diamond stability zone, they must then find their way to the surface of the earth to be mined. This occurs through violent volcanic eruptions. These eruptions send magma rapidly to the surface to relieve pressure. Only if these eruptions pass through the diamond stability zone, they can carry diamonds with them. The rock type produced by these volcanic activities is known as a kimberlite, named after the South African town of Kimberley where it was first discovered.
Panna in the state of M.P. is the only place in entire Asia, where diamonds are extracted. Diamond mine in Panna is managed under the Diamond Mining Project of National Mineral Development Corporation (NMDC Ltd) of Government of India Today, NMDC is the only organised producer of diamond in India from its Majhgawan mine at Panna, Madhya Pradesh. There is only one mine in Panna where the diamonds are found and excavation is still going on in the same mine since 18th century. Unlike other mines, the diamond mines have a volcano’s crater like open-pit shape.
The pieces of rocks are then collected at a place using heavy duty trucks. The crushers then crush the rocks in very small pieces, which after multiple stages of chemical treatments and filtration give us the most precious stone ‘The Diamond’. Four ‘C’ ie. Cut, Clarity, Colour, and Carat determine the value of a diamond. Generally at some places the photography wasn’t allowed inside the premise.
Panna is a small town near Satna in M.P. . Although not everyone is allowed to enter the NMDC premises as it is a very high security zone, still there are many points of tourists attraction near Panna. The world famous temples of Khajuraho is just 40 km away, Pandav Falls, Raneh Falls, Crocodile Farms, Nature Walk, Panna National Park are in close vicinity of Panna. Panna itself is a historical town. Many temples and few forts like Ajaigarh are near to Panna.
