Super! This amethyst geode has a bridge of chabazite crystals across it, with more geode behind. The chabazite is colourless but fluoresces a bright green colour under U/V light. The fluorescence is due to a trace amount of uranium in the molecular structure of the chabazite. Really a striking specimen! in white light OR U/V light.
