I don't have these in hand yet so I am a slave to the sellers pics. I couldn't find that marble you are speaking of in another picture.
BUT, some of the ones I found interesting are the ones I marked with arrows.
So, Steph, these larger ones (like the one I have marked with the yellow arrow) are Jabos?
The one in the second pic with the black arrow looks like it has an amber base glass. Any idea of the maker?

Now that I get a better look at that one... I looks like it has a chip out of it.....
