Our transcription: These are the rings, and let's do that process as it goes on so we can visualize it.
First, we grow a little bit of garnet.
Then we rotate the ring.
We rotate that and grow another ring and rotate it with the ring inside.
And we grow another ring and so forth until we develop, basically, a shape like this in which we have a little pit over here and a little mound over here, and the diameter of the rotation here.
We can compare that with a real specimen, which is over here, and this is a real specimen in which we see the little pit here, the little mound here, the common axis through here, and it shows a snowball pattern.
In the same specimen we can see a cross-section of a garnet that's grown considerably more than that garnet has showing that rotation.
