Famous Diamond #6: Millennium Star

I did promise that the famous diamond streak will end soon….keeping to my word, this WILL be the last famous diamond (until I come across a new one that is, haha)

Saved the best for the last! Just look at the picture below…..Its a ‘Star’ alright!

For the 6th and final time….The aptly named Millennium Star! 🙂

Millennium Star


In 1999, De Beers unveiled the De Beers Millennium Jewels – the centrepiece being the De Beers Millennium Star, a ‘D’ colour, flawless pear-shaped stone weighing 203.04 carats.

The rest of the Millennium Jewels were made up of eleven rare blue diamonds with a total weight of 118 carats.  The largest was the Heart of Eternity weighing 27.64 carats.

The Millennium Star weighed 777 carats in the rough, and is the sixth largest diamond of gem quality ever discovered. (my eyes popped out momentarily when i read this part, 777 carats!)

It took the Steinmetz Group three years to cut the Millennium Star.  First of all it was split in Belgium, then polished in South Africa and subsequently finished in New York.

Over one hundred plastic models of the stone were made to design and plan for the optimum cut for beauty and weight.  A special room had to be constructed and special tools created for the operation.

In the end the diamond was shaped into a classic pear, with 54 facets.  Harry Oppenheimer remarked that it was the most beautiful diamond he had ever seen.

The De Beers Millennium Jewels were displayed in the Millennium Dome at Greenwich in London, in the year 2000, and later at exhibitions in Tokyo and Dubai.

No wonder they call it the Millennium Star….look at the details and work that went into it…..sigh, just for a rock! Seriously! a rock!


judging from the final product, It’s worth the ‘blood and sweat’ no?

That’s it for Famous Diamonds folks!

I shall hunt for new topics to bombard you with soon 🙂

Famous Diamond #5: Golden Jubilee

Hahaha I am guess you must be getting a tad tired of reading about famous diamonds no?

I can assure you that it won’t go on forever. Just a couple more *grins*

Hey, I have to give ALL these world famous diamonds their ‘one-minute’ fame!

With that, I introduce you to the diamond version of a golden egg….the “Golden Jubilee”

Golden Jubilee

Discovered in the Premier mine in South Africa in 1986, the 755.50 carat rough diamond was a beautiful golden yellow colour with a bright reddish hue at the centre. (didn’t I say it is the diamond version of the ‘golden egg’?)

Gabi Tolkowsky commented that “within its heart lay a wonderfully mysterious shine that gave the diamond a character unlike any other”.

A large surface and deep cracks from the interior, as well as several inclusions, meant that cutting and polishing the big diamond presented challenges.

An underground room that was free from vibration had to be constructed before work could begin on the diamond.  In 1990, after two years of work, the stone was finished, reduced in total from 755.50 carats, to 545.65 carats.

Gabi Tolkowsky described the cut as a “Fire-Rose cushion shape.”

Thai businessmen arranged for the diamond to be given to King Bhumibol as a gift from the people to celebrate the 50th anniversary of the King’s ascent to the throne.

The diamond was named the Golden Jubilee, and was received by the King’s daughter, Princess Matia Chari Sirindhom, on his behalf in 2000.

The diamond is now on display in the Royal Museum at Pimammek Golden Temple Throne Hall in Bangkok.

Anyone up for Thailand? :p

Famous Diamonds #4: Eureka

Continuing from where I left off, here is another “sparkling” story which places South Africa as “diamond haven”

Enjoy! 🙂

The Eureka Diamond is perhaps the single most important diamond in the history of South African mining.

Discovered in 1866 by children digging amongst the shrubbery of their father’s land, it remained for some time “undiscovered”  – a mere plaything for the children of Dutch farmer Daniel Johannes Jacobus Jacobs.

No one in the farmer’s home took it to be anything more than an attractive rock, and it was not until a neighbour farmer, Schalk van Niekerk, who possessed a smattering of geological knowledge noticed the stone whilst visiting the Jacobs’ farmhouse.

Whilst van Niekerk did not imagine it could be a diamond he thought it interesting enough to offer to buy the Eureka from the children.  However, Mrs Jacobs refused to accept any payment and simply gave the stone to her neighbour.  (how I wish I was the neighbor! hahaha)

The Eureka then passed to John Robert O’Reilly who van Niekerk took the stone to in order to confirm his suspicions that it might be a rare mineral.  O’Reilly determined that it had to be a diamond and it was sent to Dr. William Guybon Atherstone in Grahamstown for authentication.

In 1867 Atherstone confirmed the “first” diamond to be discovered in South Africa, stating it was a “veritable diamond weighing 24 carats worth £800”, he suggested that the Eureka be exhibited at the Cape Colony’s stand at the Paris exhibition.

However it was felt that Queen Victoria should be given the opportunity of inspecting the diamond firsthand so a replica was exhibited and the Eureka was sent on its long journey to Windsor.

The stone was then sold to Sir Philip Wodehouse, Governor of the Cape Colony for £500; O’Reilly and van Niekerk sharing the proceeds.  Whilst an agreement had been made that van Niekerk would give some of his share to the Jacobs family, it seems they never received a penny for their great discovery.

In 1870 Sir Philip returned to the UK, and there the Eureka was to remain for almost 100 years. It was cut and, over the course of almost a century, changed hands a number of times.

In 1946 the Times reported that £5,700 had been paid at a Christie’s public auction for a diamond bangle of 20 large stones with the Eureka as its centrepiece.

It remained in a private collection until, in 1967, exactly 100 years after its discovery, De Beers purchased the Eureka, gifting it to the people of South Africa.

The Eureka was placed on permanent loan by the South African government at the Mine Museum, Kimberley – a fitting venue to display the gemstone that established South Africa as one of the world’s richest resources of diamonds.

Don’t you wish you found a diamond in your backyard now?…..I DO! *grins*

Famous Diamond #3: De Beers Diamond

And another famous diamond for your reading pleasure 🙂

De Beers Diamond

In March 1888, the enormous, light yellow octahedron was found in the De Beers mine

De Beers Diamond

It was cut and displayed at the Paris Exhibition in 1889.  After the removal of approximately 200 carats during cutting, its weight was 228.5 carats.

The De Beers Diamond is the 7th largest cut diamond in the world.

It was bought after being displayed in Paris, by the Maharajah of Patiala.  Cartier Paris set it in 1928 as the centrepiece of a ceremonial necklace.

In 1982, the De Beers Diamond was put up for auction at Sotheby’s, but failed to meet its undisclosed reserve.

The stone is often confused with a larger white diamond called the Imperial, Great White, or Victoria, however mathematical calculations have shown otherwise.

Famous Diamond #2: Agra

Picking up from the first post of famous diamonds, here is the next in line….Agra

If I were to describe this gem in one word, it would be “captivating”.

Introducing the Agra!


Agra is the site of the Taj Mahal, one of the most beautiful buildings in the world. The diamond has a long history, with many of the earlier accounts disputed.

It has been suggested that in 1526 the Agra diamond was taken into the possession of Babur, the first Mogul Emperor, after he defeated the Rajah of Gwalior in battle.  It is recorded that Babur wore the Agra diamond in his turban.

In 1739, the Agra may have been amongst loot captured by Nadir Shah when the Persian sacked Delhi, however the gem eventually returned to India.

The diamond was reputedly smuggled to England by young military officers in around 1857, in the year of the Indian Mutiny.  However the Agra was apparently already in the possession of the Duke of Brunswick, who had paid the huge price of 348,600 francs for the stone.

Later in the 19th century, the Agra was reduced to just under 32 carats, to eliminate some black inclusions.  Even at this stage it was questioned whether the Agra was indeed the same stone that some thought it was.

More formal records indicate that Edwin Streeter purchased the Agra from Bram Hertz, with Hertz giving Streeter over £15,000 in jewels and cash in return.

Despite a lengthy lawsuit relating to the Agra, the stone remained in Streeter’s stock until 1904 when the Parisian jewellers La Cloche Freres, put the item up for sale at Christie’s in 1905.

Shortly after 1909 the gemstone was acquired by Louis Winans, son of a wealthy American railroad engineer.  Louis Winans settled in Brighton and used a local jeweller to help him create a stunning collection of coloured diamonds.

In 1990, the Agra and two other diamonds from the collection were auctioned at Christie’s.  The vendor had inherited them in 1927, and during the Second World War had buried them in the garden for safe keeping.

The Agra was certified as a fancy light pink natural coloured VSI2, and sold for £4,070,000, making it at that time, the most expensive pink diamond in the world.

Since then, the Agra has again been recut, to 28.15 carats.

What a history! Wouldn’t it be interesting if one could travel through time and watch how all these events took place? 🙂

Famous Diamonds #1: The Centenary

There are a few famous diamonds I would like to talk about but I shall not overwhelm you with its ‘sparkling’ history. Thus I shall dedicate each post to these magnificent gems. De Beers, the frontrunner in the diamond producing industry celebrated their Centenary with style. What better way than to show the world what they dug out of their backyard (pun intended, lol)

For thousands of years diamonds have been valued for their beauty and rarity, entrancing us with their fire and brilliance. Symbols of financial wealth, power and inspiration, diamonds are also a token of love and personal expression of our hopes for the future and an emblem of eternity.

So what makes a diamond famous?  Rarity is often the most important factor.  This may mean size, but extraordinary variety or intensity of colour can also make a diamond famous.  Large flawless diamonds – those with the best colour and clarity grades – are among the rarest materials on earth.

Other factors are more closely linked to the history of the individual stone. Diamonds are often named after their owner, their country or mine of origin, their colour, their shape, a special occasion or the sentiments they evoke with their unique beauty.

The Centenary

The Centenary celebrations of De Beers took place in 1988 in Kimberley, in front of a captive audience of four hundred people. These included government representatives of producer countries and other important dignitaries from the diamond industry.  Julian Ogilvie Thompson, the then Chairman, revealed that a diamond of 599 carats had been recovered from the Premier mine.

Over time, the Premier mine had produced approximately 300 stones of more than 100 carats, and nearly 25% of all the world’s diamonds over 400 carats.  These included important stones such as the Cullinan, the Niarchos, the Taylor-Burton, and the Premier Rose.

When found in 1986, only a few people knew about its discovery, and were sworn to secrecy.  The rough stone presented many difficulties in polishing it.  One of the most accomplished cutters in the world, Gabi Tolkowsky, was chosen to study and appraise the great stone.

We have recovered at the Premier mine a diamond of 599 carats which is perfect in colour – indeed, it is one of the largest top colour diamonds ever found.  Naturally it will be called the Centenary diamond.

Julian Ogilvie Thomson

He said of its top colour – “Usually you have to look into a diamond to appreciate its colour, but this just expressed itself from the surface.  That is very rare.”

Generally, however, the rough shape of the diamond meant it would be difficult to cut, and with a number of alternative routes, including cutting the diamond into several smaller stones.

In the end Tolkowsky said the diamond was to be made into one large modern-cut stone.

Tolkowsky and two other cutters, Geoff Woollett and Jim Nash, worked with hand-picked engineers in a specially constructed room in the De Beers Diamond Research Laboratory in Johannesburg.  The construction of the room itself took a year.

Meanwhile Tolkowsky studied the diamond.  He said, “From the moment I knew I was going to cut it, I became another man, a strange man.  I was looking at the stone in the day, and the stone was looking at me at night.

Kerfing by hand, Tolkowsky took 154 days to remove 50 carats, to reveal a rounded stone weighing approximately 520 carats.  After many sketches, thirteen shapes were presented to the De Beers Board, and a modified heart shape was decided upon.

After nearly a year of work, the Centenary weighed 273.85 carats.  It also had an unprecedented number of facets, with 164 on the stone and 83 on the girdle.  Two flawless pear shapes were also cut.

The Centenary is the largest modern-cut diamond in the world, and is the ultimate expression of both “fire” and “brilliance”.

Nicky Oppenheimer remarked, “Who can put a price on such a stone?”

There you go, the first of the many famous diamonds…just look at the colors bouncing off the diamond! Magnificent! 🙂
