It is a natural giant clam pearl, notable for its enormous size and smooth surface, although it lacks the classic iridescence of smaller pearls. This pearl is more of a natural curiosity than a gem-quality pearl.

The Pearl of Puerto Galera

How to Choose
When selecting a giant pearl, consider the type of mollusk it came from, as giant clam pearls differ significantly from traditional oyster pearls in luster and shape. Size and weight are often the primary attractions for these pearls, but surface quality, shape, and rarity also matter. For collectors, provenance and documented history can add value. If the pearl is intended for jewelry, smoothness and symmetry become more important, but these giant pearls are generally prized as natural curiosities or display pieces rather than fine jewelry.
