Palawan Princess

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.

Kimberlite

The ON-K120 Kimberlite is one of the largest diamond bearing kimberlites in the world, with a surface area totalling some 102 hectares situated within claims of the FALC-JV. The largest operating diamond mine is Orapa in Botswana and the mined AK1 kimberlite has an area 103 hectares.
A resource estimate has not yet been determined for the ON-K120 Kimberlite but kimberlite tonnage estimates, which are conceptual in nature, were published in the SGF News Release of November 21, 2006. No underground bulk sampling has been undertaken to date in Orion North. It is Shore's assertion that diamond loss and diamond  breakage occur (particularly of the large stones) in the case of the LDD mini-bulk samples.
