GENEVA.- Sotheby’s will present ‘The Raj Pink’, the world’s largest known Fancy Intense Pink diamond, weighing 37.30 carats. This superb and exceptionally rare diamond will take centre stage during Sotheby’s sale of Magnificent Jewels and Noble Jewels in Geneva, on 15 November 2017. 

The discovery of any pink diamond is exceptional, but the Raj Pink’s remarkable size and intensity of colour places it in the rarefied company of the most important pink diamonds known.” David Bennett, Worldwide Chairman of Sotheby’s International Jewellery Division 

MAJESTIC PRESENCE 
The rough diamond which yielded ‘The Raj Pink’ was studied for over a year after its discovery in 2015. It was then entrusted to a master cutter, who brought the diamond’s innermost beauty to full display by crafting it into a sparkling cushion-modified brilliant cut. 

The Raj Pink’ was named by the current owner of the diamond, who wishes to remain anonymous. It is based on the Sanskrit word for ‘king’. 

The Gemological Institute of America (GIA), which certified the diamond, characterized it as an “astonishing stone”, describing its hue as “a very bright and ravishing fancy intense pink color”. It continued, “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. 

Only on the rarest occasions do diamonds with vibrant, shocking color like the Raj Pink’s emerge… only the most privileged and knowledgeable in the industry know of their existence. With an unmodified Fancy Intense Pink hue, substantial size and desirable clarity, the Raj Pink is certainly one of those gems that only few may have the honor of experiencing.” --Gemological Institute of America.

NoteFor most coloured diamonds, the hue comes from impurities that accidently interfere during the formation of the crystal at hundreds of miles deep in the earth. A diamond is mainly composed of pure carbon; it is the intrusion of another trace element that impacts the colour, such as nitrogen for yellow and boron for blues. The pink colour, on the other hand, may be the result of a distortion of the crystal structure that has yet resisted the attempts of explanation by science.

Pink fancy coloured diamonds are rare in nature, particularly those of large size. According to the GIA, the annual global pink-to-red diamond recovery could fit on the palm of one’s hand. The astonishing stone offered in this auction displays a combination of very bright and superb fancy intense pink colour. One can find different levels of colour intensity; the brilliance, hue and size of this precious gem are truly exceptional.

The current record price ever achieved at auction for a diamond or any gemstone is 'The Pink Star’: one of the world's great natural treasures later renamed ‘CTF Pink Star’. This magnificent Fancy Vivid Pink diamond weighing 59.60 carats was sold at Sotheby's Hong Kong in April 2017 for $71.2 million.

The current record price per carat and for any Fancy Intense Pink diamonds was set by ‘The Graff Pink’ weighing 24.78 carats, sold in Sotheby’s Geneva in November 2010 for $46.2 million.

Cutting & Polishing

Discovered and mined in South Africa in 2015, the rough crystal was studied with extreme precision during the course of one year before it was passed to the hands of a master cutter.

The original rough

“In observing the Raj Pink in its final form – a sparkling 37.30 carat cushion modified brilliant – one may fail to recognize the work behind its transformation from rough to polished. Though nature granted the gem with rare colour fine clarity, it was the cutter who capitalized on these qualities and brought the diamond’s innermost beauty to full display… 

Though a diamond is crafted with the knowledge that it will be observed in a particular orientation (what is referred to as ‘’face up’’), all aspects of its three-dimensional structure must be accounted for in optimizing that directional appearance. While the shape of the rough often suggests the diamond’s final shape, the art of cutting is as much an organic process as it is a balancing act: a cutter must maximize the weight retention while creating a stone with the best possible colour and clarity… 

GIA’s research throughout the years has found the cushion brilliant shape and cutting style effectively channel and intensify the colour appearance of coloured diamonds. The cushion’s slightly curved sides and rounded corners give visual balance to the precise, hard-edged geometry often associated with the diamond faceting of today. Intricately cut, triangular and kite-shaped facets interact with light and produce flashes that enliven and enhance the diamond’s overall appeal. Lastly, it is not unusual for cutters to modify a cutting style in efforts to produce the most desirable appearance in a coloured diamond”.

Colour

“For a diamond to display strong, unmodified pink colour like that observed in the Raj Pink is rare, particularly so at a considerable weight; the larger the diamond, the less likely it is to appear saturated by a deep hue”. 

Excerpts from the GIA monograph

“Only on the rarest occasions do diamonds with vibrant, shocking colour like the Raj Pink’s emerge. Their origins and discoveries are often held as closely guarded secrets, and only the most privileged and knowledgeable in the industry know of their existence. With an unmodified, Fancy Intense pink hue, substantial size, and desirable clarity, the Raj Pink is certainly one of those gems that only few may have the honour of experiencing”.
