THE LARGEST PEARL IN THE WORLD, the Pearl of Allah or the Pearl of Lao Tzu as it is now called, has a length of 9.4 inches and weighs 14 pounds and is found in the Philippines.  It got its original name from a Muslim diver who found the pearl with its surface having an image of a turbaned face so he named it “Pearl of Allah”.

It is not a gem-quality pearl, but is instead what is known as a “clam pearl” or “Tridacna pearl” from a giant clam.

Gemologist Michael Steenrod in Colorado Springs has appraised the pearl at $60 million (1982) and $93 million (2007).
