Sotheby’s is set to offer the Historic Pink Diamond for sale on 12 May.
The diamond is set to feature at the Magnificent Jewels and Noble Jewels auction in Geneva, Switzerland, on 12 May.
Sotheby’s classes the Historic Pink Diamond as extremely rare and important, and this fancy vivid pink diamond is believed to have been part of the collection of Princess Mathilde, niece of Napoleon I, according to the Gemmological Institute of America (GIA). The stone boasts VS2 clarity and mesmerising colour.
The 8.72-carat stone has a classic non-modified cushion cut, unusual in a pink diamond. Its estimate is US$14–18 million. Last October, Sotheby’s achieved a price of US$17.8 million for a Fancy Vivid Purplish-pink diamond weighing 8.41 carats.
Also featured in the sale is the Sunrise Ruby by Cartier, which is pigeon’s blood red, untouched by heat treatment and described by the Swiss Gemmological Institute as a “unique treasure of nature”. It weighs 25.59 carats and has an estimate of US$12–18 million.
Other Cartier jewels include a diamond necklace, featuring diamonds totalling more than 190 carats (estimate US$6–10 million); a brooch set with a 30.23-carat sapphire from Kashmir (estimate US$3.5–6 million); and a pair of elegant sapphire and diamond earrings, made with two exceptionally well-matched Burmese Mogok sapphires of 15.77 and 16.90 carats, respectively (US$800,000–1.2 million).
The auction also includes jewels from the Estate of Mary, Duchess of Roxburghe, granddaughter of Rothschild heiress Hannah and British Prime Minister the Earl of Rosebery. The collection includes three stunning tiaras, along with a selection of fine jewels.
David Bennett, worldwide chairman of Sotheby’s International Jewellery Division, said: “I have remained in awe of the Sunrise Ruby since the first moment I set eyes on it. In more than 40 years, I cannot recall ever having seen another Burmese ruby of this exceptional size possessing such outstanding colour. We are also very excited to be offering a world-class fancy vivid pink diamond, dubbed the ‘Historic Pink Diamond’ by the GIA, along with a remarkable wealth of signed pieces, including a private collection of extraordinary jewels by Cartier. We’ve had a tremendous response from those who’ve viewed the wonderfully rich selection to be offered in our Geneva sale.”
