Interesting Fact - Diamonds

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.)
