Divided Core Swirls have, as the name indicated, a core comprised of separated bands.
There will be at least three and as many as six bands.
On the latter type, the bands may be situated in such a manner as to give the appearance of lobes if the core is observed from above.
I have found the marble information and condensed this on one page.

Latticinio Swirls are the most common type of hand made glass marble.
Compared to most other handmade marbles, Latticinio Swirls have little value, though there are several factors that can increase their value, other than large size and/or rarity of colors (especially core color).
