Sierra Leone diamond (Kono region)

The Sierra Leone Diamond is a 709-carat, alluvial diamond found in 2017 by workers hired by Pastor Emmanuel Momoh in river sediment in Koidu village, Kono district, Sierra Leone. It has since been renamed The Peace Diamond.
Discovery.
The Peace Diamond was discovered on 13 March 2017 by a team of five diamond miners. The miners brought the diamond to Pastor Emmanuel Momoh, manager of the Majestic Exploration & Mining Company Limited and owner of the mineral concession licence.
Momoh found the diamond while searching through river sediment in a community artisanal licence area belonging to the community of Koyardu Village within the mineral exploration concession licence of Majestic Exploration & Mining Company Limited. He is not a professional diamond hunter. He looks for diamonds as a freelancer or "artisanal" diamond hunter. Momoh said that he had the option of fleeing to Belgium with the diamond using the help of a local dealer. However, he handed over the diamond to the government with the hope that it would help increase recent development in the country, and especially the impoverished Kono district.
The diamond.
The uncut found diamond is slightly smaller than a hockey puck. It is one of the twentieth largest ever found and the largest discovered in the past forty years. It is the second largest found in Sierra Leone, the largest being the Star of Sierra Leone, a 968.9-ct diamond discovered in 1972. The diamond appears to have a reddish stain coating it. The Ministry of Mines and Mineral Resources has attempted to clean it by "boiling (it) in hydrofluoric acid and nitric acid for 72 hours".
Auction.
Ernest Bai Koroma, president of Sierra Leone, stated that the Ministry of Mines was given "clear instruction to the Ministry of Mines that the evaluation, sale and distribution of the proceeds must be done in the most transparent manner." He also said that Momoh, who is officially its present owner, would be given a certain amount of the proceeds after the diamond is sold at auction. Momoh has been involved in the weighing, cleaning, and bidding of the stone, and states that he is satisfied with the transparency of the process.
The diamond is now in a safe at the Bank of Sierra Leone, Sierra Leone's central bank in Freetown.
By April 5, 2017, there had only been six offers for the diamond. In response, the deadline was extended to May 10.
