Seems like I am the only person who loves opals.
have you heard of Eric the Opalised Pliosaur? Back in 1993, when it looked like he would be sold overseas, a TV science program started an appeal to raise enough money for him to be kept in Australia. Within a few weeks $450,000 had been raised much of it coming from fundraising efforts of schoolchildren including my own children who donated their allowance. The Australian Museum ended up with him and they had so much money left over that Eric was able to go on a nationwide tour. My kids loved being able to see him with their own eyes. He is very beautiful, I don't think any photos of him do him justice.
