Huge 'peace diamond' believed to be one of the biggest ever found sells for £4.9 million

  • Stone is 709-carat and was unearthed in Sierra Leone in March
  • Between the 10th and 15th biggest diamond ever found in the world 

A huge so-called 'peace diamond' sold by the government of Sierra Leone to discourage crime-tainted 'blood diamonds' was sold for £4.9 million ($6.5 million) on Monday.

The 709-carat stone, which was unearthed in March, is the largest discovered in Sierra Leone in almost a half-century.

The diamond is said to be the 14th-largest ever discovered, according to the Rapaport Group, which auctioned the stone in New York on behalf of Sierra Leone's government. 

Found by a company led by evangelical Pastor Momoh, the diamond was given to the government in the hopes it would handle the sale in a way that leaves more profits and development potential in Sierra Leone.

Named the Peace Diamond, £2.8 million ($3.8 million) of the proceeds will directly benefit 250,000 inhabitants of a Sierra Leone region with no school, hospital, clean water or roads

British jewelers Laurence Graff purchased the stone, according to Martin Rapaport, whose group hosted the auction. The government was expecting about £5.25 million ($7 million).

'Perhaps we're dealing with the price of transparency,' Rapaport said.

Illegal mining and sales of so-called blood diamonds have been a major source of strife in many African countries including Sierra Leone. That was the goal of the auction approach of President Ernest Bai Koroma.

Expectations at home were high, yet the price may have seemed a disappointment.

Gibril Sesay, a market seller, said he wanted the government to provide 'water, electricity and good roads for the people' with the proceeds of the gem following the sale.

But Beatrice Cole, a civil servant, told AFP 'the money paid for the diamond was far below what we expected' after watching the auction live on TV in Freetown.
