If you need something special and Clare’s Accessories just isn’t doing it, then a recent auction in Hong Kong may have had just what you’re looking for. The Hong Kong branch of Christie’s Auction House recently said ‘sold’ to a diamond that’s described as ‘the size of a ping-pong ball’.
Set in a tiara was a 101.27 carat shield-shape diamond that had been cut from a 460-carat rough. The mega-rock, while internally flawless, has a slight imperfection on the surface that is imperceptible to the human eye, according to the auctioneers. Imperfect or not, a private buyer was ready to shell out over $6.1 million for the sparkling headset.
It is the largest colorless diamond to appear on the auction market in the last 18 years, Christie’s said. Only three colorless diamonds of more than 100 carats have appeared at auction. All were sold in Geneva. Naming rights were granted to the new owner – suggestions welcome……
Did you know that the biggest diamond ever found is really out of this planet. I mean that. There’s a star somewhere out there which is in fact a mega-diamond, reportedly weighing 10 billion trillion trillion carats. In other words, bigger than big- some 4,000 kilometers in diameter.
Don’t expect this diamond though to ever find its way to a diamond dealers’ scales as it’s some 50 light years away from earth.
“You would need a jeweler’s loupe the size of the Sun to grade this diamond,” says astronomer Travis Metcalfe, of the Harvard-Smithsonian Center for Astrophysics, who led the team of researchers that discovered it.
The huge cosmic diamond – technically known as BPM 37093 – is actually a crystallized white dwarf. A white dwarf is the hot core of a star, left over after the star uses up its nuclear fuel and dies. It is made mostly of carbon. The space diamond (apparently a ‘she’) was christened Lucy in a tribute to the Beatles song ‘Lucy In The Sky With Diamonds.’
Astronomers expect our Sun will become a white dwarf when it dies 5 billion years from now. Some two billion years after that, the Sun’s ember core will crystallize as well, leaving a giant diamond in the center of the solar system.
“Our Sun will become a diamond that truly is forever,” says Metcalfe.
The cosmic stone completely outclasses all diamonds that have ever been found on Earth. The largest diamond weighing 546 carats was found in South Africa. The diamond, The Star of Africa, resides in the Crown Jewels of England. The Star of Africa was cut from the largest diamond ever found on Earth, a 3,100-carat gem.
