What happened to my Cat is right Art, that marbles's a mess! And glued back together? Someone probably thought it was a shrunken core Onion Skin or some nonsense -looks Asian to me but I don't think I've seen another that large so I'd be thinking Vacor too.
Something about it looks off to me. I'm not really seeing CAC, but I am not sure what I am seeing. Whatever it is, a Vacor Rooster, a JABO, it seems all kinds of messed up to me.
Most Moss Agates don't usually have filaments- just uniformly "cloudy", although some, like Lime Ades and kin, can have more stringy white. The shape of the patch and the seams are also different.
