What is the name of the largest gem-quality natural pearl known?

The largest gem-quality natural pearl known is the Pearl of Lao Tzu, also referred to as the Pearl of Lao Tze or the Great Pearl. This remarkable pearl measures around 9.45 inches (around 24 cm) in length and was discovered in the Palawan Sea in the Philippines. Its size, weight, and historical significance contribute to its status as one of the most notable natural pearls in existence.

La Pelegrina, while famous and intricately tied to royal histories, is not the largest pearl; it is, however, significantly smaller than the Pearl of Lao Tzu. The Dudley pearl, while noteworthy, is also not as large as the Pearl of Lao Tzu. The Queen of Pearls is a name that has been used for various large pearls through history, but again, it does not refer to the largest gem-quality natural pearl recognized today.

Understanding the Pearl of Lao Tzu helps underscore its unique qualities not just in size, but also in its rich provenance and significance in the world of gemology.
