Largest Round Diamond Ever at Auction

On Dec. 17 in New York City, Sotheby’s will offer what it calls the largest round diamond ever sold at auction—and at 110.92 carats, it’s hard to argue.

Unlike the 163 ct. D-Flawless emerald-cut about to be sold by Christie’s, the Sotheby’s stone doesn’t offer specs to die for. It’s been graded L color (faint light brown) and VS1 clarity, though it has excellent polish, cut, and symmetry. Sotheby’s hopes to fetch between $4.2 million and $6.2 million for it.

But this whopper stone is not even the highest value item Sotheby’s plans to sell in December. It’s also offering a 5.69 ct. fancy vivid blue diamond ring (pictured, below). That carries a $12 million to $15 million estimate.
