The previously unheard-of extraordinarily large natural blister pearls Pearl of the Queen of Tribal Nations that weighs 9 kilograms and the Pearl of the Brown Emperor weighing more or less 14 kilograms. There are also several other natural pearls of nearly the same weight but these are by far the biggest known in the whole world. Both natural blister pearls came from the south west portion of the Philippine Islands and may have grown to their present size for no less than a hundred years. The two largest natural blister pearls are exquisite in form and beauty. Photographs of the pearls are shown below:
