The world's largest uncut diamond found by a pastor says he expects to get "not less than $50 million" for the 709-carat precious stone.

Failing to reach its minimum reserve price at auction in Sierra Leon, Pastor Emmanuel Momoh declared "I want my diamond to be sold abroad so I can get the best price to enable many people to benefit from the proceeds."
The highest bid, for $7.8m, came from a UK citizen based in Antwerp, the European diamond capital in Belgium. Another auction is expected to take place in a few weeks.
The undisclosed reserve price, was set by the Sierra Leonean government.
May 2016, diamond-mining firm Lucara sold a 813-carat stone for $63m (£51m) at a closed auction in London.
