Clockwise spin on some here, just pics at my disposal. The MCR/MCS types do seem to spin counter clockwise more than clockwise but the other pelts seem to be more 50/50.
There are plenty. If you understand how the marbles are made, you can see that the spin can occur either way. Look at all the Pelt ram's heads... they have clockwise AND counter clockwise spin on the same marble even.
What size is it? Transparent green base guinea cobra? With strandy filaments from one end of the ribbon to the other, bleeding transparent colors? I don't see it.
Not polished, not end of cane. Often one or both pontils were treated a bit by the maker, especially on the nicer and bigger ones. Flame polishing, faceting, etc...
I would say they aren't as common as their usual cateyes but they are common enough. They are very appealing to me though, the glass looks so different, like wax or something in the vanes.
I got the reply that not all the red and blue ones glow and not to use that as an identification trait on this type. And this one photo and I cropped the original tray to about the same area.
