(Gemmolgical laboratories must discern the finest stones from one another) Fewer than one in every 100,000 diamonds meet the criteria fancy-vivid. With a well-balanced and entirely pink colour saturation and an even colour distribution, the GIA (Gemmological Institute of America) awarded the Winston Pink Legacy the ultimate colour grade of ‘fancy-vivid’ pink.
The majority of pink tones contain some form of secondary colour, most commonly including purple, brown, orange or grey, however the Winston Pink Legacy has been certified as containing no such colour modifier. Type IIa account for less than 2 percent of the pink diamonds certified by the GIA and other leading gemmological laboratories each year around the globe. Vivid pink diamonds, such as the Winston Pink Legacy, are described as Type IIa diamonds, that is to say these gemstones have very low to nil trace of nitrogen and they are said to be among the most chemically ‘pure’ diamonds, with exceptional transparency and lustre. It’s unbelievable!” Diamonds are divided into Type I and the extremely rare Type II, examples of which have a highly desirable near homogenous colour saturation. You may see this colour in a pink diamond of less than one carat but this is almost 19 carats and it’s as pink as can be.
Rahul Kadakia went on to say of the Winston Pink Legacy that “the saturation, the intensity of this stone is as good as it gets in a coloured diamond, to find a diamond of this size with this colour is pretty much unreal. (The Christie's Magnificent Jewels auction is an annual event that attracts worldwide interest) The auction as a whole witnessed bids from over 51 countries, covering all 6 habitable continents of the globe, and achieved total sales of $110.2 million. In addition to the Winston Pink Legacy a number of other lots, including natural pearls and items once belonging to famous collectors, far exceeded their reserves. In the words of Rahul Kadakia, Christie’s international head of jewellery: “this exceptional diamond captured the imagination of international collectors across the globe, with more than 30,000 people visiting Christie’s sale previews to see this remarkable stone, it has taken its rightful place among the world’s greatest diamonds.” What is even more surprising is the fact that the bidding only lasted for 5 minutes before the hammer went down! Nayla Hayek, CEO of Swatch Group, Harry Winston, later went on to state that “We are proud to continue in the Winston tradition of acquiring the finest gems in the world and tonight the Winston Pink Legacy joins our incredible legacy collection, which began with the acquisition of the 101-carat, D Flawless Winston Legacy diamond at Christie’s in 2013.” Furthermore, the sale marked the highest price achieved by any single item at any Geneva auction house in the month of November 2018. At 18.96 carats the Winston Pink Legacy sold for US$50.3 million in the Magnificent Jewels sale at Christie’s Geneva. In November 2018 a new world record price per carat was set at auction for a pink diamond when the “Winston Pink Legacy went under the hammer, achieving US$2.6 million per carat. Winston Pink Legacy – the most expensive pink diamond per carat in the world forges a new trend
