I need to clean out some room, so I'll let go of some Zicme's of mine. In the dome there is a rock and it expanded with some cracking and chipping. 5/8 at the widest point. There is also a ISC 5/8 X 1/2, but there is an under poor in the inner skirt. It has one small chip off the wire grove. There are tons of bubble, some amber and a rock in the glass. The rock is right by "Zicme", and is 1/2 big. $60, plus shipping. Or all three Zicmes for $170
