Largest pearl

What to remember

A giant clam in the Philippine Sea yielded this pearl to a Filipino fisherman's family from Puerto Princesa. At 170,000 carats, or 34 kg, the Pearl of Puerto is the largest known pearl.

Its shape is unusual. Like the Pearl of Allah, the previous largest pearl, it lacks the usual round shape: it measures 67 cm long and 30 cm wide. It stayed out of sight for years and was only shown to the public in August 2016, about a decade after it was found.

One point is worth noting: the pearl has not been authenticated. The record therefore rests on its mass and dimensions, without authentication.
