When most people think of fossils, they imagine bones turned to stone, but in certain parts of the world fossils take on a much more colourful and dazzling form. These are opalised shells, ancient marine remains that have transformed into shimmering gems over millions of years.
 
To put it into perspective just how rare these are, only 1 in 1,000 organisms fossilise, for a fossil to opalise this statistic is reduced to 1 in 100,000!
