Sotheby’s will offer the largest round diamond ever sold under the hammer at its next Magnificent Jewels and Fine Jewels auction.

Being auctioned on December 17 in New York City, the round brilliant stone is 110.92cts. While it is a far cry from some of the rough stones and other cut styles which have gone before, Sotheby’s claim this will be the largest round brilliant to go under the hammer.

The auction house hopes to fetch between $4.2 million and $6.2 million for the stone which has been graded L in colour, with a VS1 clarity and an excellent polish, cut and symmetry.


Expected to fetch more money is a 5.69ct fancy vivid blue diamond ring, which is carrying a $12 million to $15 million estimate.

Gary Schuler, chairman of Sotheby’s Jewellery Division, comments: “We’re thrilled to present supreme examples of the world’s most sought-after jewels and gemstones this season, led by the stunning fancy vivid blue diamond ring and the 110.92-carat round diamond. Greatly admired for their rarity, these are gems that are enthusiastically pursued by collectors and connoisseurs.”
