The auction also featured jewels from popular brands, including Cartier, Chopard, and Tiffany & Co."This beautiful diamond ring was one of the most popular items in our jewelry auction," said Ben Randall, senior specialist and catalogue manager at Fellows. "This alluring piece of jewelry shot above its auction estimate and it received a huge amount of bids. The ring is simply stunning, and the...diamond attracts your eyes whenever you are in its presence. It was no surprise to see such strong interest in the ring."Image: The 4.86-carat diamond ring.
