You're looking at the "Arco Valley Pearl," which at 575-carat and 3.1 inches in length is the largest natural pearl in the world.
The pearl, which once belonged to the descendant of Chinese Kings, Genghis Khan, and even Marco Polo, is being auctioned. If you have a spare $8 million you can buy it for yourself.
