Bonhams and Butterfields will auction off what is believed to be the world's second-largest documented pearl, a five-pound gem found off the coast of the Philippines that has been dubbed the "Palawan Princess."The natural non-nacreous pearl was found in sal****er near the Philippines' Palawan island and "bears an uncanny resemblance to a human brain," the auction house said. Both rare and immense, the gem is thought to be surpassed in size only by the 14-pound "Pearl of Allah," an approximately 14-pound, 31,893.5-carat pearl that, like the Palawan Princess, was the product of the giant clam shell Tridacna gigas and was also found off the coastal waters of the Philippines.
