The 59.60-carat, “Pink Star” diamond previously known as the “Steinmetz Pink” diamond was cut and polished by master cutters of the Steinmetz Group in 2003, from a rough stone weighing 132.5 carats, mined by De Beers from an unidentified African mine in 1999, and subsequently acquired by the Steinmetz Group. The finished diamond was unveiled in Monaco on May 29, 2003, at a public ceremony, and was briefly worn around the neck of super-model Helena Christensen. The “Steinmetz Pink” diamond was exhibited at the “Splendor of diamonds” Exhibition held at the Smithsonian’s National Museum of Natural History, in Washington D.C. between June 27th and September 30th, 2003. It was again put on display at the “Diamonds” exhibition, held at the Natural History Museum in London, between 8th July 2005 and 26th February 2006.

The “Steinmetz Pink” diamond was first sold to an anonymous buyer for an undisclosed sum, by a privately negotiated sale by its owners the Steinmetz Group in the year 2007. The new anonymous owner of the diamond renamed the diamond, the “Pink Star” diamond. The anonymous owner of the “Pink Star” diamond entrusted the auction house Sotheby’s to sell the diamond at its Geneva “Magnificent Jewels Sale” that was held on November 13, 2013. A pre-sale estimate of US$ 60 million was placed on the “Pink Star” diamond, which was widely expected to be surpassed at the auction, given the unprecedented demand for high-quality pink diamonds at that time, and the fact that a pink diamond of lesser color grade – fancy intense pink – and less than half the weight of the “Pink Star” diamond, viz. the 24.78-carat, fancy intense pink “Graff Pink” diamond – registered a record price of US$ 46 million at a Sotheby’s auction also held in Geneva in November 2010. The final hammer price did indeed surpass the estimated US$ 60 million and the “Pink Star” diamond sold for an unprecedented US$ 83 million at the Sotheby’s Geneva auction on November 13, 2013, the highest ever price realized by any jewel at a public auction. However, not long after the sale it was reported that the consortium of buyers, led by diamond cutter Isaac Wolf, who successfully bid for the diamond at the auction, reneged on the purchase, which was confirmed by Sotheby’s in February 2014, which stated in its annual report that the diamond was still part of its inventory, and valued at US$ 72 million. It is believed that the auction house had bought back the diamond from its owner/seller as it had guaranteed that price to the anonymous owner/seller of the diamond.

Sotheby’s announced in June 2016, that it has entered into a partnership with two other firms for the diamond, viz. Diacore Group of Companies Ltd. (formerly Steinmetz Group of Companies Ltd.) and Mellen Inc. Diacore, is a multinational company, with diversified interests in the diamond industry, as a supplier of rough and polished diamonds to customers around the world and manufacturing facilities in Botswana, South Africa, Namibia and New York, renowned for crafting rare, exceptional diamonds as well as unique high- end jewelry. The 203.04-carat De Beers “Millennium Star” diamond and the magnificent 59.60 carat, flawless fancy vivid pink “Pink Star” diamond are both creations of Diacore. Mellen Inc. is a third generation, family-run private jeweler based in New York.

Sotheby’s on behalf of the two investors on the Pink Star diamond and on its own behalf, is putting up the 59.60 carat, internally flawless, fancy vivid pink, oval mixed-cut diamond for sale again at its Hong Kong Magnificent Jewels and Jadeite Spring Sale coming up on April 04, 2017. Currently, the most valuable diamond ever sold at a public auction is the 14.62-carat “Oppenheimer Blue” diamond, which fetched a record-breaking price of US$57.5 million at a Christie’s Geneva Sale held on May 18, 2016. However, given the fact that the “Pink Star” diamond is more than double the weight of the 24.78-carat “Graff Pink” diamond, which set the world record price of US$ 46 million for a pink diamond ever sold at an auction, at a Sotheby’s auction in Geneva in November 2010 and even has a better color-grade of fancy vivid than the said diamond, while at the same time having a clarity-grade of Internally Flawless, it might not be surprising if the “Pink Star” diamond not only sets a new world record for a pink diamond sold at an auction but also a new world record for any diamond/gemstone or for that matter any single jewel sold at an auction.

In Chinese culture, carps symbolize strength and power and abundance. Exemplifying freedom and vitality, the combination of fish and water has enraptured Chinese art since antiquity.

SAPPHIRE HIGHLIGHTS

Some of the sapphire highlights include Lots 1795, 1656 and 1793

Lot 1795 - Important Sapphire and Diamond Ring
Lot 1795 – Important Sapphire and Diamond Ring

Lot 1795 is a Kashmir or Ceylon sapphire lot, titled, “Important Sapphire and Diamond Ring,”with a pre-sale estimate of HKD 4,000,000 – 5,000,000 (USD 515,520 – 644,400). The size 5½ platinum ring is double claw-set with a 8.64-carat, rectangular emerald-cut,violetish-blue Kashmir or Ceylon blue sapphire flanked by two half-moon-shaped colorless diamonds. The ring is stamped Pt 950 for platinum. The color of the sapphire is slightly violetish blue of medium strong saturation and eye-clean. However, under x10 magnification, there are some typical natural inclusions. characteristic of both Kashmir and Ceylon sapphires.

Two contradictory lab reports accompany the lot. One lab report by the internationally renowned Gübelin Gem Lab, numbered 17011088, dated 3 February 2017, state that the sapphire is natural and of Kashmir origin, with no indications of heating. An appendix letter attached to the report, further states “the natural sapphire possesses a richly saturated and homogeneous color, combined with a high degree of transparency, and a finely proportioned cut. In addition, this remarkable gemstone has been spared of thermal treatment. Such a combination of characteristics is rare in natural Kashmir sapphires of this size.”

A second lab report issued by an equally renowned laboratory, The Swiss Gemological Institute (SSEF) numbered 90874, dated 9 March 2017 states that the sapphire is natural, of Ceylon (Sri Lanka) origin, with no indications of heating. The color of this sapphire may also be called ‘royal blue’ based on SSEF reference standards.

The apparent contradiction in the two reports is perhaps due to overlap of characteristics, such as common inclusions found both in Kashmir and Ceylon sapphires, and the violetish-blue/cornflower-blue found mainly in Kashmir sapphires but sometimes also in Ceylon sapphires originating in certain regions such as Elahera, as reported by Richard W. Hughes, the world renowned gemologist and author of the book “Ruby & Sapphire.” However, its important to remember that the apparent contradiction in the two reports does not in any way compromise the value of the sapphire, as the quality of the sapphire in terms of its color, saturation, transparency, clarity, cut, rarity etc are all excellent be it a Kashmir or Ceylon sapphire.

Lot 1656 -Sapphire and Diamond Ring
Lot 1656 -Sapphire and Diamond Ring

Lot 1656 is another significant sapphire lot, with a pre-sale estimate of HKD 2,500,000 – 3,200,000 (USD 322,200 – 412,416) and titled “Sapphire and Diamond Ring.” The size 6½ platinum ring is set with a 24.50-carat, cushion-shaped Burma blue sapphire of medium blue color of strong saturation, flanked by two pear-shaped colorless diamonds.

Two lab reports by SSEF and GGL numbered 80236 and 17021112 respectively, state that the 24.50 carat sapphire is natural; of Burmese (Myanmar) origin; and with no indications of heat enhancement. Sapphire contains typical inclusions only visible under 10x magnification. Estimated total weight of diamonds 0.65 carats; color-grade E to F and clarity-grade VS, as gauged and graded in the mounting.

Each of the pair of ear studs is set with a matching cushion-shaped blue sapphire, weighing respectively 3.51 and 2.70 carats.

Two AGL reports numbered 1082622 and 1082621, both dated 13 March 2017, state that both the sapphires are natural, with no indications of heating, and the 2.70 carat sapphire is of Kashmir origin, but the origin of the 3.52 carat sapphire was not determinable. However, Gübelin Gem Lab report numbered 17011089/ 1 and 2, states that both the sapphires are natural, of Kashmir origin, with no indications of heating, and contain typical inclusions not visible to the naked eye.
