Rare Pink Diamond on the Auction Block

  • Jill Newman

For the past two years, exceptional-quality colored diamonds have been breaking auction records, thus there are great expectations for the rare 24.78-carat fancy intense pink diamond that Sotheby’s is offering as part of its Magnificent Jewels sale in Geneva on November 16. The emerald-cut pink diamond ring (with a pre-sale estimate of between $27 million and $38 million) is classified as a type IIa, which comprises less than 2 percent of all of the world’s gem diamonds, and the Gemological Institute of America stated that the stone may be internally flawless after repolishing. “This is quite simply one of the most desirable stones I have ever seen,” said David Bennett, chairman, Europe and the Middle East, Sotheby’s International Jewelry Department.

There are several other important diamonds at the Geneva auction including a 20.16-carat square step-cut Graff diamond ring; a 20.18-carat emerald-cut diamond ring from Harry Winston; and a 4.59-carat intense pink diamond ring, in addition to other signed pieces and jewelry from the estate of Christina Onassis, the only daughter of Greek shipping tycoon Aristotle Onassis, who passed away in 1988 at age 37.
