A defective swirl

This smaller marble on the right

and also in a second photo showing closer views.

There is a very noticeable crease where the clear and yellow/amber color is supposed to fill in that gap.

There is no damage and I wonder how this could have happened?

Maybe two different temperatures in the mix?

ID would be appreciated. 1/2 inch or maybe just a tad larger. THANKS!

It was smaller, so it didn't fit tight in the roller grooves and it cooled down too much to smooth out completely as it went down the rollers. If the volume of the ingot was greater, then it would have fit the rollers better and probably smoothed out better. By the time the ingot passes 5 or 6 grooves of the rollers, it has already hardened too much to smooth out much more.
