Interesting Fact - Diamonds

Astronomers at the Harvard-Smithsonian Center for Astrophysics, have discovered the largest diamond in the galaxy. It is 10 billion trillion trillion carats.

(It measures 4,000 km across, and lies some 50 light-years from the Earth in the constellation Centaurus. It's actually a crystallised white dwarf, the compressed heart of an old star that was once bright like our Sun but has since faded and shrunk, and the carbon interior has solidified to form the galaxy's largest diamond. It is technically known as BPM 37093, but astronomers have decided to call it "Lucy" after the Beatles song, Lucy in the Sky with Diamonds. According to Travis Metcalfe, the leader of the team who discovered it, you would need a jeweller's loupe the size of the Sun to grade it.)
