Philippines: A tourism official says a Filipino fisherman in western Palawan island has found possibly the world’s biggest pearl, which he had hidden under a bed for 10 years as a lucky charm.

Aileen Amurao, Puerto Princesa city’s tourism officer and the fisherman’s relative, said Thursday the man gave her the 34-kilogram (75-pound) pearl that’s 2.2 feet (67 centimeters) long and 1 foot (30 centimeters) wide for safekeeping. She says she was shocked to learn from the internet that it could be the world’s biggest.

The fisherman, his father and brothers found the irregular-shaped pearl inside a giant clam that stuck to their boat’s anchor when they sought refuge from a squall.

The pearl is displayed in the city hall, and the fisherman will receive a reward from the local government.
