Stalactitic chalcedony geode (repaired) Fossil the white quartz layer fluoresces

the white quartz layer fluoresces white and the calcite has a strong orange-red reaction with phosphorescence

I’d love to learn more

which is unusual given that it typically forms on the quartz surface (I didn't do the best job of photographing it
