Interesting Facts

The world's most expensive diamond (to date) was sold at Sotheby's in Geneva, for ... wait for it - £52m. (The Pink Star, which would look good on any Barbie doll, is supposedly the largest internally flawless fancy pink vivid diamond (measuring 2.69cm x 2.06cm) that the Gemmological Institute of American has ever graded. Estimated to sell for at least £38 million, the diamond attracted four bidders and finally sold for $83,187,381 (£52, 024,735.83), which is a world auction record for a diamond and any gemstone or jewel. You can watch the insanity here:- )

According to scientists from the University of Wisconsin-Madison and Nasa's Jet Propulsion Laboratory, 1,000 tonnes of diamonds a year are being created on Saturn. (These diamonds, which are big enough to be worn as jewellery, could be raining down on Saturn and Jupiter. Seemingly, lightning storms turn methane into soot (carbon) which, as it falls, hardens into chunks of graphite and then diamond. And you just thought it was a rock.  Remember - rock is slang for a diamond or other gemstone.)
