Over 2 consecutive nights in May, two exceptional diamonds are set to be auctioned, and both are likely to break auction industry records.
First up, on the 17th May, is Sotheby’s Magnificent Jewels and Nobel Jewels Geneva auction. Amongst the line-up of outstanding jewels and gems is one particular beauty, a 15.38ct pear-shaped pink diamond.
Sotheby’s describes the “Unique Pink” as “supremely rare and exceptional” and auctioneers expect the gem to sell for between $28 – $38million. Officially the largest pear-shaped vivid pink diamond ever to be auctioned, the stone has been graded by the GIA (Gemological Institute of America) as a “vivid” colour, the highest possible colour grade.
The “Unique Pink” is also a Type IIa diamond, the purest form of diamond possible. Argyle, the world’s largest diamond mine situated in Western Australia is the world’s most noted supply of pink diamonds, which are exceptionally rare.
The following night, on the 18th May, Christie’s will host it’s Magnificent Jewels sale, also in Geneva. The most talked about item from this auction is the “Oppenheimer Blue”, a spectacular 14.62ct emerald cut blue diamond.
Like pink diamonds, blue diamonds are exceptionally rare and stones of vivid colours and large sizes fetch huge market prices. The “Oppenheimer Blue” is the largest and finest fancy vivid blue diamond ever to be offered on auction, according to auctioneers Christie’s.
Pre-sale estimates of $38 – $45million could bring the Oppenheimer Blue very close to the record $48.5million reached by the sale of the 12.03ct Blue Moon diamond last year. The Oppenheimer Blue has a VVS1 clarity, compared to the internally flawless clarity of the Blue Moon.
The Oppenheimer Blue is being sold as it is currently set, in a platinum ring, flanked on each side by trapeze-shaped diamonds. The stone is named for it’s former owner, Sir Phillip Oppenheimer, chairman of De Beers’ Diamond Trading Company until he passed away in 1995.
Previously, Sotheby’s announced that it would be auctioning a 9.54ct blue diamond from the collection of the late Shirley Temple, on April 19th at it’s New York Magnificent Jewels auction. Pre-sale estimates for this stone range from $25 – $35million.
