The Largest Pearl Ever Found
The largest pearl ever found is the Pearl of Allah, also known as the Pearl of Lao Tzu. It weighs approximately 14.1 pounds (6.4 kilograms) and measures about 9.45 inches (24 centimeters) in diameter. This massive natural pearl was discovered in 1934 in the Palawan Sea, Philippines, inside a giant clam. Its size and origin make it the largest verified natural pearl ever recorded, surpassing all other known specimens in weight and dimensions.
The pearl's current estimated value is not publicly fixed, but experts often cite its potential worth at over $40 million to $100 million depending on market conditions and authentication. It is considered a unique natural treasure rather than a standard jewelry piece. The value stems from its unprecedented size, natural formation, and historical provenance.

Discovery and Origin
The Pearl of Allah was found by a Filipino diver named Wilbur Dowell Cobb in 1934. He discovered it inside a large Tridacna gigas clam off the coast of Mindoro, Philippines. The pearl was later named by a local chieftain, and its origin in a giant clam is a key factor in its record status. The clam species itself can live over 100 years, allowing such massive pearl formation over decades.
The pearl's discovery story involves a mix of local folklore and documented history. It was initially kept by Cobb before being acquired by a collector. Its journey from a remote Philippine island to international attention highlights the rarity of such finds. The geographic origin in the Sulu Sea remains a critical part of its identity as the largest natural pearl ever documented.
Record Status and Comparison
The Pearl of Allah holds the official record for the largest pearl ever found by weight and size. It surpasses the previous record holder, the Pearl of Lao Tzu, which is a different specimen and often confused in historical accounts. Modern gemological surveys confirm its status, and it is frequently cited in authoritative lists of world records for natural pearls. Its dimensions remain unmatched by any other single natural pearl discovered to date.
While cultured pearls dominate the modern market, the Pearl of Allah is a rare natural wonder. Its existence challenges typical pearl size expectations, as most gem-quality pearls are under 2 inches in diameter. The record it holds is specific to natural formation without human intervention.
