However, the lot that will take center stage at the Magnificent Jewels and Noble Jewels sale in Geneva on November 15, 2017, will be “The Raj Pink,” diamond, the world’s largest known Fancy Intense Pink diamond, with a clarity-grade of VS1, weighing 37.30 carats, mounted on a platinum ring with an estimate of CHF 19,250,000 – 29,000,000 (USD 19.7 – 29.7 million). The Raj Pink rough diamond discovered in 2015, was transformed by a master cutter, after an extensive study that lasted for over an year, into an exceptional cushion-modified brilliant cut diamond, that brought the diamond’s innermost beauty into full display. GIA which certified the diamond, described the “Raj Pink” as “an astonishing stone with a very bright and ravishing fancy intense pink color.” It further stated “For a diamond to display strong, unmodified pink color like that observed in “The Raj Pink” is rare, particularly at so considerable a weight.” The discovery of a gem-quality pink diamond of any size is an extremely rare occurrence. Of all diamonds submitted to the GIA each year, less than 0.02% are predominantly pink. The “Raj Pink” diamond was unveiled in London on 13th October, 2017 and was displayed alongside other highlights from the Magnificent Jewels & Noble Jewels sale, until 17th October, 2017.
