I have a several Geodes. One of the things me and the kiddo like to do when we go to the ren fair, is buy a “dragon egg” to crack. And we have done that at the gem and mineral show as well. She keeps a half and I keep a half. Sort of the geek version of the two heart half locket.
You can see a couple of them here on my thread towards the bottom. They are florescent!
