This giant pearl could be the biggest ever found after being handed in by a fisherman.
The Daily Mail reports that the man, who has not been identified, found the priceless 34kg gem 10 years ago in sea off the coast of Palawan Island, Philippines.
He didn't know its potential value of US$100 million ($137m) and kept it as a "good luck charm".
The Daily Mail reports that a fire at his home this year forced him to move.
The fisherman handed it in to the tourism officer in Puerto Princesca who verified that it had been found in a giant clam.
