Amber, Clear then Green based marbles are my experience with this type of “Germans”.
I would call this one red rather than orange based on the images. I have never held one or seen one in person but I think that the ID is right on.
As far as UV reaction goes—I am not too sure about these types—nuff said.
Nice size, nice condition—just not CAC imho.
A very nice find!
Nice marble, thanks’ for sharing it.
Marble—On!!
