The Perfect Pink Diamond – US$23.2 Million


Christie’s Hong Kong sold its highest priced jewel at the autumn sale on Monday, November 29, 2010. A rare 14-carat diamond called the “The Perfect Pink” was sold for HK$179.9 million ($23.2 million), the most expensive in Asia, after an intense bidding session.

Lot Description

Set with a rectangular-shaped fancy intense pink diamond weighing 14.23 carats, flanked on either side by a rectangular-shaped diamond weighing 1.73 and 1.67 carats, mounted in 18k rose and white gold, ring size 5½.

Accompanied by report no. 14432611 dated 16 May 2005 from the Gemological Institute of America stating that the 14.23 carat diamond is fancy intense pink, natural color, VVS2 clarity, with excellent symmetry.

Accompanied by a note no. 1009543 dated 24 September 2010 from Gübelin Gemmological Laboratory stating that diamonds are classified into two fundamental groups based on the relative presence or absence of nitrogen incorporated into the crystal structure, as determined by the infrared spectrum. Type I diamonds contains appreciable concentrations of nitrogen, whereas type II diamonds are chemically very pure and do not reveal infrared absorption characteristics related to nitrogen. A further separation of these two groups includes type Ia (nitrogen atoms present in pairs or groups), type Ib (isolated nitrogen atoms), type IIa (no measurable traces of nitrogen) and type IIb (traces of boron). Based on its infrared spectrum, the diamond of 14.23 carats is classified as a type IIa diamond.

Also accompanied by two reports no. 2125332554 dated 21 July 2010 and 17550927 dated 3 August 2010 from the Gemological Institute of America stating that the 1.73 and 1.67 carat diamonds are D color, internally flawless clarity.

The Perfect Pink

Gem connoisseurs have long considered pink diamonds to be among the most beautiful of gemstones since they were first discovered in the ancient mines of India.  Larger specimens rarely come up for auction and their scarcity makes the sale of The Perfect Pink, a 14.23 carat fancy intense pink diamond, an extraordinary event. Indeed, large polished pink diamonds with this intensity of color are virtually unheard of– in fact, fewer than 10% of pink diamonds weigh more than 0.20 carats.

Beyond its impressive size, The Perfect Pink is a paragon of perfection in terms of its color, clarity, and cut. While most pink diamonds exhibit a color modifier like purple, orange or grey, this specimen shows absolutely no trace of a secondary color, making it exceedingly rare, both commercially and naturally.  Only this requisite richness and depth of its inherent pure pink body color combined with a wonderful balance of tone and saturation can qualify for that coveted Fancy Intense color grading from the Gemological Institute of America (GIA). While the majority of pinks are graded SI (Slightly Included) on the GIA clarity rating scale, this 14.23-carat pink diamond shows no inclusions. Its VVS2 (Very Very Slightly Included 2) grading is due to an internal graining, typical of Type IIa pink diamonds such as this.  Further emphasizing its rarity is the elegant and classic rectangular cut of the diamond, a cut generally reserved for white diamonds.  Rather than a modified cut seen in the vast majority of color diamonds – used to help “release” color – the impeccable emerald cut signals that no additional facets were required to intensify its perfect tone.  Taken together, The Perfect Pink is unmatched and stands as a diamond of the highest caliber fit for the world’s most discerning collectors.
