Pink and blue diamonds have achieved some of the highest prices on the auction circuit in recent years. Here are a few of the top sellers:
The CTF Pink
Sotheby’s described this oval-shaped, 59.60-carat, fancy vivid pink, internally flawless diamond as “a true masterpiece of nature” in the run-up to its sale. When it sold to Chinese jewelry chain Chow Tai Fook, the final hammer price certainly lived up to the hype, more than doubling the previous record price for a fancy vivid pink diamond.
Sold for $71.2 million (HKD 553 million) at Sotheby’s Hong Kong on April 4, 2017.
The Oppenheimer Blue
At 14.62 carats, this is the largest vivid blue diamond ever to come to auction, and its sale last year caused quite a stir. The emerald-cut stone takes its name from previous owner Sir Philip Oppenheimer of De Beers fame. Christie’s chairman François Curiel called it “the gem of gems.”
Sold for $57.5 million (CHF 56.8 million) at Christie’s Geneva on May 18, 2016. 
Blue Moon of Josephine
Property tycoon Joseph Lau bought this as a gift for his seven-year-old daughter, though chances are, he has the cushion-shaped, 12.03-carat, fancy vivid blue diamond under lock and key until her years outstrip the stone’s carats. It will sit nicely next to her other blue diamond, the 7.03-carat Star of Josephine.
Sold for $48.4 million (CHF 48.6 million) at Sotheby’s Geneva on November 11, 2015.
The Princie Diamond
This is a stone of controversy. When the cushion-cut, 34.65-carat, fancy intense pink diamond surfaced and subsequently sold, Italian millionaire Amedeo Angiolillo was far from pleased. He claimed it was an Indian diamond that had passed through his family and mysteriously gone missing, and he sued the auction house over it.
Sold for $39.3 million at Christie’s New York on November 25, 2009.
The Zoe Diamond
When it sold, this pear-shaped, 9.75-carat, fancy vivid blue diamond broke not one, but two records. It set a new record price for the sale of a blue diamond (which has since been trumped), and it achieved the highest price per carat of any diamond in auction history.
Sold for $32.6 million at Sotheby’s New York on November 20, 2014.
