of Palawan Island, Philippines, the fisherman found the enormous clam while trying to dislodge his boat's anchor that was wedged on it. Fisherman found world's largest Pearl worth $100million and kept it under his bed for 10 YEARS This giant pearl could be the biggest ever found in the world and five times larger than the previous record - after being handed in by a fisherman. The man, who has not been identified, found the priceless 34kg gem ten years ago in sea off the coast of Palawan Island, Philippines. He didn't know the potential eye-watering value of $100 million and kept it as a 'good luck charm' in his rundown wooden home.But a fire at the property earlier this year forced him to have a clear out and move house. The fisherman handed it in to the stunned local tourism officer in remote Puerto Princesca who verified that it had been found in a giant clam. The priceless rock measures a staggering 1ft foot wide and 2.2 feet long - dwarfing the current world's biggest Pearl of Allah which weighed 6.4kg and is worth $35million.
