The Top 10 Jewelry Auction Sales So Far in 2016
Fancy blue diamonds dominated the spring auction season, led by the 14.62-carat Oppenheimer Blue.

New York--So far, 2016 has been one for the record books when it comes to the auction world.
This spring auction season achieved more than $800 million in sales between the months of March and July, according to a recent article from the Gemological Institute of America. Christie’s and Sotheby’s, the two largest auction houses for high-end gem and jewelry sales, broke last year’s half-year record by more than $140 million.
Fancy colored diamonds and colored gems continued to set records across the world as they hit the auction block, with one blue diamond, the “Oppenheimer Blue” becoming the most expensive jewel ever sold at auction in May.
And that hasn’t been the only notable blue stone to go up for auction this year. In fact, in the top 10 lots alone in the first half of 2016, five were fancy blue diamonds.
There also was a 15.38-carat pear-shaped fancy vivid pink diamond that sold for more than $31 million, as well as the “Aurora Green,” which set the world auction record for a green diamond. Rounding out the top 10 were two ruby pieces and a pair of earrings featuring two fancy vivid orange-yellow oval diamonds.
Had Lesedi la Rona sold at auction, it would’ve topped the list--the 1,109-carat rough diamond was estimated at $70 million, but bidding at the June 29 auction held by Sotheby’s London didn’t reach the reserve price.
Here’s what the jewelry auction world has been up to so far in 2016, with the top 10 lots in descending order.
