Fluorescence under black light! ῍̻̩✧*˖῍̻̩̻̩✧
Most of the blue is coming from fluorite; I have a lot of that.
The yellow is calcite, and the lowermost four in the last photo are all chalcedony. Love that ghostly glow.
Strangely though, one of those has some weird veining and darker colors coming from it… :O!
