Featured Sherman Brooch Glows Green

Hi All,
Here it is 2AM and it is flipping hot, my dogs can't rest which means I'm up. We've just came back from a walk, so now I'm wide awake. I'm taking photos of stuff and noticed this brooch is glowing green with the blacklight. A signed Sherman brooch, the lavender rhinestones are glowing which I wouldn't expect. Is this unusual?
any information appreciated.
thanks for looking

 

Very nice brooch, cx.
I only knew that from yellowish-greenish rhinestones, but it is probably something similar.
Here is an explanation of the fluorescence in rhinestones:

sweet..........hope you got some sleep....

 

thanks AJ Yes, the yellow/green I've seen, was just surprised with this one.

thanks komokwa got a few hours in!

 

Hope the dogs had fun. Mine loves going out at night, but when she was a pup, she cried if we tried to take her beyond the porch light. Had never experienced that with any of the other pups, so there was a learning curve for all of us.

 

Yeah, hot here in the carolinas as well, how hot is it? the water for my morning coffee is lukewarm! THANK GOD! for air conditioning!
Sorry, i know nuttin about jewelry

 

Would those be color-changing lavender stones? Do the change to bluish during the day in different lighting (inside, outside, incadenscent, etc.)?

 

thanks Marko Sherman did some Alexandrite rhinestone pieces but this isn't one of them.
