Catalogue Note

Accompanied by GIA report numbered 1162202561, dated 27 June 2014, stating that the 8.41 carat diamond is natural, Fancy Vivid Purple-Pink colour, Internally Flawless clarity, with Excellent Polish; further accompanied by diamond type classification report stating that the diamond is determined to be a Type IIa diamond. Type IIa diamonds are the most chemically pure type of diamond and often have exceptional optical transparency. Also accompanied by a signed box.

Most pink diamonds through the formation process tend to have less than desirable clarity and also tend to suffer from an inherent trait of internal graining, which affects the brilliance and luster. This 8.41 carat pink diamond is remarkable for its very crisp crystal and internally flawless clarity as well as being “highly transparent and very clear”. This diamond is rare for its size, beautiful hue, and exemplary rich saturation of colour.

“A coloured diamond is a touchstone of the universe, a little something God created that man can’t always find…they are the last frontier of collectable.” – R. Winston 1986

The story of this pink splendor was set nowhere else but in the ancient mines of South India, the land blessed with the world’s purest and most famous diamonds, and the only source of diamonds known to men before the 18th century. Jean Baptiste Tavernier, a French merchant and adventurer who was best known for acquiring the Tavernier Blue Diamond the he subsequently sold to Louis XIV, first made a reference to rose diamonds in early 17th century. According to Tavernier’s account, this enormous pink rough weighing over 200 carats was shown to him by moguls in kingdoms of Golconda in 1642 during his second voyage to the East. Valued at 600,000 rupees almost four hundred years ago, this diamond named ‘The Grand Table’ is still the largest pink diamond known to date. In his book ‘The Six Voyages’, he later drew a picture of two pale rose coloured diamonds that he purchased in India circa 1668.

Many of the world’s most famous pink diamonds, such as The Darya-i-Nur, Agra, Le Grand Condé, The Hortensia and Shah Jahaan, very likely originated in the famous Kollur mines, near Golconda in Southern India, adorning crowns and jewels of kings and moguls during that period. Some made their journeys into Europe and were sold or presented as largesse to monarchs and the royals. The exact source of some other famous ones is not known, and some quite large pink diamonds have been recovered from alluvial deposits in the interior of Brazil and Africa in more recent times.

Natural pink diamonds over a carat are extremely rare to come by; some would say it is beyond rare. The famous ‘Williamson’ pink, currently part of the British Crown Jewels, was presented to Princess Elizabeth (now Queen Elizabeth II) on the occasion of her wedding on 20 November 1947. Taking its name from its finder, Dr. J.T. Williamson, this pink diamond is one of the most illustrious modern day finds from South Africa. In the late 1980s, encouraging soil samples led geologists in search of diamond mines to North West Australia. After a decade looking through kimberlite sites, they finally discovered the Argyle mines, which now supply approximately 90% of the world’s pink diamonds. Yet, despite this significant discovery, their paucity remained stupefying. Only 0.1% of the twenty million carats of rough produced annually is pink, and a whole year's worth of production of these pink treasures over half a carat would fit in the palm of your hand. The majority of the produce qualified as ‘pink’ are usually around twenty points and of low clarity.

Currently there are no other pink diamond mines in the world, and any discovery of pink diamond deposits would take at least a decade’s time up to the actual production. As this rare treasure draw more and more attention from gem connoisseurs and aficionadas around the world, the demand of the alluring pinks far exceeds the supply. Whenever a pink diamond over 5 carats is put up at an auction, it naturally assumes a pivotal position in the auction room, drawing waves of approving gasps when it fetches astronomical prices time after time. It does not take an expert to admire this nature’s marvel, and their dreamlike colour never disappoints. That, is the magic of pink diamonds.


It is widely known that diamonds are formed by carbon atoms bonded together in a crystalline lattice that does not absorb any wavelengths of light, thus affording it a white or more accurately, colourless appearance. The whiter its colour, the more precious it is, such is the belief of the majority, because purity is that ultimate rarity. Yet fewer would understand that it is exactly these ‘impurities’, which gemmologists call ‘trace elements’, that account for the vibrant array of hues found in natural coloured diamonds. Each colour is nature’s unique recipe, and only the most subtle balance of ingredients can culminate in a substantial beauty too mesmerizing to be true.

Nitrogen and boron are the contributing factors to yellow and blue colours in diamonds; pink, however, kept its own secret far beyond comprehension of researchers. Natural pink diamonds have what is known as a defect centre. With enough of these defect centres the diamond may take on different properties, such as absorb certain wavelength of green light, lending it a pink appearance when light reaches our eyes. How this exactly happens still baffle gemmologists and scientists around the world.

What researchers are sure of is that one or more of the carbon atoms in the diamond lattice may be missing or replaced with a different element in the defect centres. This is a result of plastic deformation of the diamond during its geologic history in the earth, usually when it is in semi-solid state. Layers of carbon atoms that are parallel to the orientation of the applied stress are displaced slightly along gliding planes. These glided planes of atoms appear needle-like and are known as pink grain lines or pink graining.

The concentration of these bands of graining is directly related to the strength of the pink colour, the more graining there are, the more intense the pink colour. Hence, the critical conditions required for the formation of pink diamonds and the passage as they travel to reach earth surface often result in less than desirable clarity. It is fair to say that pink diamonds come naturally with a certain extent of graining. The linear pattern of surface graining can sometimes be moderately visible; whereas internal graining may give the diamond an overall hazy appearance. For a pink diamond to exhibit a homogenous and saturated pink colour without the obvious shortcoming of graining, a very delicate balance must be achieved, needless to say, completely shunned from human intervention. At the pinnacle of Mother Nature’s mastery is this 8.41 carat fancy vivid purple-pink diamond, displaying not only an evident sweet pink colour, but to be hailed for its exceptionally rare internally flawless clarity with no graining whatsoever and of a most beautiful hue of pink of intense saturation. True perfection, by all odds.


“Crystal” is a term that is sometimes used in gemmology to describe the appearance of top quality gems that is ‘highly transparent and very clear’. The 8.41 carat Fancy Vivid Purple-Pink diamond is a gem that the term crystal is aptly applied. It is a rare combination of size and saturated colour with an Internally Flawless clarity grade.
- Tom Moses, GIA Senior Vice President of Laboratory and Research

“Mined by De Beers, and fashioned from a diamond rough of over 18 carats, and through meticulous cutting and polishing, this flawless 8.41 carat vivid purple-pink diamond is a remarkable gift from Mother Nature, through Man’s creative aspiration and technical mastery.”

“Pink is adored for its flattering feminine colour : it is the gentle flakes of cherry blossoms in Springtime April; it is delicate cotton candy floss melting at the tips of innocent fingers: it is the cheeks of a new-born tucked into a soft woolly quilt; or a precious dream sailing on chartaceous carnations.”
