Two months ago I heard the story of a pastor from Sierra Leone who discovered a large diamond. The good pastor, Emmanuel Momoh, handed over the 706-carat diamond to the Sierra Leonean Government for valuation and subsequent sale. Pastor Momoh was to benefit from part of the proceeds of the sale of the diamond.
I am not an expert in the sale of diamonds but imagine if this "Momoh diamond" was sold at an auction in one of the European or US cities by a lone auctioneer without any security. If you heard that such an auctioneer was robbed of the "Momoh diamond", you would probably think he was not wise to attempt selling such a precious commodity without requisite security.
