The Top Auction Sales of 2015
From rare and colored to large and flawless, many of the diamonds sold this year at auction were world record-breakers.

New York--Large colored diamonds, deeply hued rubies and colorless diamonds proved to be the most sought-after gems at auction this year, with all three comprising the top 10 jewels sold at auction in 2015.
The results are not unlike last year’s; in 2014, the jewel that fetched the highest price at auction was the “Zoe Diamond,” a 9.75-carat fancy vivid blue that sold for $32.6 million. A blue diamond also took the No. 1 spot for 2015, but upped the ante as far as size and price goes--the “Blue Moon of Josephine,” a 12.03-carat fancy vivid blue diamond graded as internally flawless, sold for $48.5 million at Sotheby’s Geneva in November.
A diamond called the “Sweet Josephine,” purchased by the same buyer for the same individual, sold for $28.5 million at Christie’s Geneva, also in November. The 16.08-carat cushion-shaped fancy vivid pink diamond ranked third overall for the year in terms of highest price paid for a gem at auction, with the “Sunrise Ruby,” a pigeon’s blood-red 25.59-carat ruby, coming between the two colored diamonds.
Aside from the high-achieving jewels that set world auction record after record this year, a few more “fun” lots also made it into the news. Among them was the 24-karat gold leaf grand piano that once belonged to Elvis Presley, which sold for $610,000 in November. There also was the Omega Constellation wristwatch Elizabeth Taylor gave to Richard Burton, which pulled in $12,000 at a sale in September, and “Yorick,” the skull carved from a meteorite, which failed to sell at a Bonhams auction in November.
