Blue diamonds are among the rarest—and, some feel, most beautiful—diamonds out there, and that was reflected in two better-than-expected auction results this week.
Following some mixed auction results last month, two big blues racked up nice prices at the most recent Christie’s and Sotheby’s jewelry auctions in New York City.
One 5.69 ct. fancy vivid blue diamond ring (pictured, right) sold for $15.1 million ($2.66 million a carat) at Sotheby’s on Dec. 5, topping its previously announced $15 million estimate.
At Christie’s, the top seller was a twin-stone (one 3.36 cts, the other 2.71 cts.) fancy-vivid blue diamond ring by Graff (below), which sold for $12.5 million, or $2.01 million a carat. That significantly beat its $6.5 million to $8.5 million estimate.
