A*nother exceptional rough diamond of 196 Carat is found in the Letseng Legacy mine on 24 August 2010
*Again an exceptional rough diamond of 507-carat (exactly 507.55 Ct) is unearthed last week at the Cullinan mine in South Africa (where the famous Cullinan diamond was discovered in 1905)
This remarkable diamond will yield a record-breaking polished stone of the very best white colour and clarity.
*One of the rarest fancy vivid blue diamond, cut from the 26.58 carat rough stone was discovered in 2008 at Petra Diamonds’ Cullinan diamond mine in South Africa. This is one of the rarest blue diamonds ever found on earth. It is an internally flawless, cushion-shaped diamond weighing 7.03 carats.Expected to be sold at $5.8 to 8.5 million on Sotheby’s auction in May 2009 at Geneva View picture of this blue diamond This rare blue diamond discovered at the same Cullinan mine, last April 2009, was sold at auction in Hong Kong for a world record of more than US $ 10’000’000,00

The Biggest diamond is found out of Earth
By Stephen Cauchi, Science Reporter
Confirming what the Beatles always knew, astronomers have actually found a diamond in the sky – directly above Australia. It is the biggest known diamond in the universe, in fact.
According to American astronomers at the Harvard-Smithsonian Center for Astrophysics, a white dwarf star in the constellation of Centaurus, next to the Southern Cross, has been found to have a 3000-kilometer-wide core of crystallized carbon, or diamond.
It weighs 2.27 thousand trillion trillion tonnes – that’s 10 billion trillion trillion carats, or a 1 followed by 34 zeroes. The biggest earthly jewel is one of the British crown jewels, the 530-carat Star of Africa.
However, this cosmic jewel is hidden beneath a layer of hydrogen and helium gases, with the diamond core making up between 50 and 90 per cent of its mass. “It’s the mother of all diamonds,” said astronomer Travis Metcalfe, who led the team of researchers that studied the star.
“Some people refer to it as Lucy, in a tribute to the Beatles song Lucy in the Sky with Diamonds.”
Known officially as BPM 37093, the star confirms a theory, first raised in the early 1960S, that cool white dwarfs should have a diamond core.
A white dwarf is what small stars, those up to about the size of the sun, turn into when they run out of nuclear fuel and die.
The intense pressures at the heart of such dead stars compress the carbon into diamond.
But confirming this theory has only been possible recently.
Lucy “pulsates”, which means its light fluctuates at regular intervals. “By measuring these pulsation’s, we were able to study the hidden interior of the white dwarf, just like seismograph measurements of earthquakes allow geologists to study the interior of the Earth,” Dr Metcalfe said.
“We figured that the carbon interior of this white dwarf has solidified to form the galaxy’s largest diamond.”
This means that other white dwarfs must also have diamond cores. Our own sun will become a white dwarf when it dies in 5 billion years. Two billion years after that, its ember core will crystallize as well, leaving a giant diamond in the center of our solar system.
Vince Ford, a research officer at Mount Stromlo Observatory near Canberra, said astronomers, including Australians, had observed the star for more than eight years.
The star is about 50 light-years away (500 trillion kilometers) – a fair distances as far as stars go. This means it is about 400 times too faint to see with the naked eye.
Are big diamonds rare or not? A very good investment if you know how to buy !
Don’t think you can buy diamonds just cut at your size. Diamonds are very rare!
The yearly world production of cut rarest diamonds with
Color: Exceptional White + (D)
Clarity: Loupe Clean (IF)
Weight: from 1 to 1.39 Carat,
is less than 900 Carat per year !
That means that – all together – there are about 750 stones available only!
To produce these 750 diamonds, the mining companies have to dig more than 800,000,000 Ton of Kimberlite. (Kimberlite are the rocks in which rough diamonds are found)
That makes the prices of rough and cut diamonds expansive and explains also the rareness of them on the market.
