The Largest Diamond in the Galaxy: 10 Billion Trillion Trillion Carats

Astronomer Travis Metcalfe and colleagues discovered the largest diamond ever floating happily in space:

Astronomers discovered the largest diamond of all times in space. The weight of the precious stone reportedly makes up ten billion trillion trillion carats or five million trillion trillion pounds).

The space diamond is virtually an enormous chunk of crystallized carbon, 4,000 kilometers in diameter. The stone is located at a distance
of 50 light years from Earth, in the Constellation Centaurus.

Scientists believe that the diamond is the heart of an extinct star that used to shine like the Sun. Astronomers have already dubbed the space diamond as Lucy in a tribute to the Beatles song ‘Lucy In The Sky With Diamonds.’
