The sale of the 74-year-old Shatner's kidney stone was organized by the online casino site GoldenPalace.com, the Associated Press reports. "This takes organ donors to a new height, to a new low, maybe. How much is a piece of me worth?" said Shatner. GoldenPalace.com CEO Richard Rowe called the actor's contribution "a bold new addition to our fleet." "This would be the first Habitat for Humanity house built out of stone," joked Darren Julien, president of Los Angeles-based Julien's Auctions, which handled the sale.

Shatner reportedly passed the stone last fall. It was so big, he said, that "you'd want to wear it on your finger." He added, "If you subjected it to extreme heat, it might turn out to be a diamond."
