Digest this. It is 2,500 miles across, weighs five million trillion trillion pounds and is, hold your breath, a diamond!
But even the heaviest moneybag in the world can't buy it for his love because it is 50 light years away (500 trillion kilometres).
Space scientists discovered the ten billion trillion trillion carat diamond on Valentine's Day buried in the core of a white dwarf star in the constellation Centaurus, The Times, London, reports
"It's the mother of all diamonds," Travis Metcalfe, who led the team of researchers at the Harvard-Smithsonian Centre for Astrophysics in America, told the newspaper. "You would need a jeweller's loupe the size of the Sun to grade this diamond."
The diamond has been named Lucy after the Beatles' song Lucy in the Sky with diamonds.
The largest diamond found on earth was the 3,106-carat Cullinan. It was cut into nine major stones, including the 530-carat Star of Africa, the largest gem diamond, now a part of the Crown Jewels.
Diamonds were first discovered in India more than 2,800 years ago.
