There in the Palawan Island sea coast, the biggest and most beautiful pearl was found almost ten years ago.
It was all a coincidence, when a fisherman threw his anchor and it got stuck into a rock during a storm.
"He noticed that it was lodged on a shell and swam down to pull up the anchor, and also brought the shell with him. This was a decade ago and he kept it at home,” said Tourism officer Aileen Cynthia Amurao.
"He didn't know how much it was worth and kept it tucked away at home as a simple good luck charm,” he added.
As he was forced to move to another house amid a fire, the man decided to have it in to the stunned local tourism officer in remote Puerto Princesca.
The priceless rock measures a staggering 1ft foot wide and 2.2 feet long and is worth more than $100 million - dwarfing the current world's biggest Pearl by five times.
"He didn't know how much it was worth and kept it tucked away at home as a simple good luck charm.
"We were amazed when he brought it to us. We now need help from gemologists to fully certify it.
"But we believe Puerto Princesca is likely to earn another prestigious title and a record breaker for having the world's biggest natural giant pearl from a giant clam.” Amurao added.
The gem was shown off to the public in Philippines on Tuesday.
