World's Biggest Diamond Bid Battle

Ever seen a tennis ball-size gem? Look at this tensional gem which didn’t find a new owner at Sotheby’s London. Worth as much as $US86 million, the 1,109-carat white diamond was discovered in the Lucara mine of South Africa last fall. Final remark – this is not the first time for Sotheby’s to put a stone for auction!
