This is the Lesedi La Rona. It's the second-largest gem-quality rough diamond in the world.
The uncut 1,109-carat stone is the size of a tennis ball. And no one wants it.
Well, no one wants to pay the estimated $70 million price tag for it.
The stone was found last fall at a mine in Botswana. Experts thought it would break the record for most expensive diamond.
That record was set in May when an 813-carat rough diamond sold for $63 million.
The Lesedi La Rona diamond went up for sale at Sotheby's on Wednesday. The highest bidder offered $61 million — below the auction house's minimum reserve price.
For now, the massive rock will remain in the ownership of the company that found it.
