Puerto Princesa City Tourism Officer Aileen Cynthia Maggay-Amurao shared a photo of the nearly 75 pound pearl, as she had sought help from gemologists to have it certified for its authenticity.

Maggay-Amurao told local news outlet Palawan News the man was not aware of the pearl's value and kept it as a good luck charm before entrusting it to her, because it was too heavy for him to bring along as he moved to another part of the province. According to the Guardian, the pearl is 1 foot wide, 2.2 feet long and worth an estimated $100 million. The pearl was placed on public display at New Green City Hall starting on August 22, and Maggay-Amurao hopes it will drive more tourism to the city.
