Wow - the Grateful Dead's 13-point thunderbolt, IN AN OPAL, which is BEING MUNCHED by Paul's classic People Eater style! How good is THAT!! Such a seriously sweet marble, and you won't believe how clean this opal is encased. I literally didn't think it would be possible to encase an opal with that many points on it without catching at least a few bubbles, but somehow Paul pulled it off magnificently. And then you have those killer colors throughout this marble, with the tri-color teeth chomping away inside the eater. You can see clear through this marble, SO awesome to explore!
