A fisherman in the Philippines did the latter after unearthing a 34kg pearl from under the sea off Palawan Island 10 years ago.
WHAT would you do if you discovered a pearl worth millions of dollars?
Since he had to shift to another region in the province, he handed over the pearl to his aunt, Aileen Cynthia Maggay-Amurao, who is a tourism officer with the local government. He chose to swim down and pull up the anchor himself and, to his surprise, found the gem.
The world's biggest pearl might have been discovered almost a decade ago, but no one knew about it until now. 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.
"We're waiting for authentication from Gemologist Institute and other worldwide authorities".
The pearl is now on display at Puerto Princesa City Tourism Office as a tourism attraction.
The enormous pearl is 1 foot wide, 2.2 feet long and weighs 75 lbs.
She said the pearl would remain in the Philippines and hopefully help attract more tourists to Puerto Princesca.
The Palawan Islands are well-known for their huge pearls.
Giant clams, which rarely produce pearls, can grow as large as four feet in length and weigh 500 pounds.
The 14-kilogram "Pearl of Allah", also known as the "Pearl of Lao Tzu", is often referred to as the world's largest.
If confirmed, the world's largest pearl would dwarf the current record holder by more than 60 pounds.
The pearl is bigger than the last recorded biggest pearl, both the pearls have been attained from Palawan Island, which is a home to majority of the pearls found.
