The huge emerald cut diamond is mounted to a platinum band, with an additional two triangle shaped diamonds weighing 2.92 carats flanking the central stone. It sold for $2.1m, making a 16.9% increase on its $1.8m high estimate.

The ring was consigned from the collection of philanthropist George Rothman. Prior to the sale, Sotheby's director of jewellery, Gary Schuler, commented: "This diamond is the calibre of stone that is sure to generate early excitement in the global jewellery market this auction season."

The diamond is 'potentially internally flawless'

Selling for the exact same sum at the auction was a pear-shaped diamond weighing 15.10 carats, flanked by two smaller 2.00 carat diamonds and mounted to a platinum band. It was accompanied by an original working diagram stating that the diamond may be potentially internally flawless.

On October 7, Sotheby's will welcome two extremely important diamonds to its Hong Kong showrooms. An 118.2 carat white diamond is expected to see $25m-30m, while the world's largest fancy blue diamond - The Premier Blue - may set a record per-carat price.
