A 10.64-carat fancy vivid purplish pink internally flawless diamond is the top lot of Sotheby’s Hong Kong Magnificent Jewels and Jadeite sale on October 7. Its estimate is $19.1 – $25.5 million.
Sotheby’s says this gem is rare in size, quality and color. Only one percent of all pink diamonds graded by the Gemological Institute of America are larger than 10 carats. In addition, fewer than four percent of all pink diamonds are considered “fancy vivid,” which is a measure of its strength of color. It’s the highest rating in the GIA fancy colored diamond scale.
The auction house further says this gem is polished as a radiant cut, with the outline of an emerald-cut diamond combined with the scintillation of a brilliant-cut diamond.
It is one of three exceptional diamonds that will be part of the sale at the Hong Kong Convention & Exhibition Centre. An 80.88-carat colorless diamond with “excellent color and clarity” is one of only five emerald-cut diamonds exceeding 80 carats ever to have been offered at auction. The diamond is D color, with exceptional transparency, according to the auction house due to being cut from a Type IIa rough gem, which represent less than 2% of all diamonds mined. Its estimate is $12.8 – $19.1 million.
