De Beers is one such company and it announced a significant find on Wednesday - though not of diamonds. The company believes it has located a treasure ship that could date back to the 15th century. The ship was laden with thousands of gold coins and a hoard of more than 50 elephant tusks.
"If the experts' assessments are correct, the shipwreck could date back to the late 1400s or early 1500s, making it a discovery of global significance," said Namdeb Diamond Corp., a joint venture between De Beers and the Namibian government.

De Beers, the world's biggest undersea diamond miner, said its geologists in Namibia found the wreckage of an ancient sailing ship still laden with treasure, including six bronze cannons, thousands of Spanish and Portuguese gold coins and more than 50 elephant tusks.
