Some Latticinio Swirls are "naked," that is, lacking an outer design.
However, most have such an outer layer and this almost always consists of either single colored strands or multicolored bands.
The other traits that apply to solid core swirls also apply to divided core swirls.
That is, examples may be "naked," "caged," "trilevel," or even "four-leveled." Some Divided Core Swirls have bands that are very close together but still have observable spaces in between them; these are considered "closed" Divided Core Swirls, an oxymoron that is really only useful in differentiating them from true solid core swirls.
The color of the core is white, yellow, orange, red, green, and blue, in increasing order of rarity.
On rare occasions there will be two colors in the core, and usually these colors alternate.
The strands may be all of one color, alternate within the set, or be in sets of alternating colors.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.Solid colored cores often have strands on their surface, either straight or twisted around the core.End-of-cane examples have a design that terminates somewhere inside the marble without reaching the other side; since they are the last marble off the cane there will only be one pontil, and it is from this that the design originates.These are rare because most marbles from the end of the cane were mis-shaped or just not very pleasing to the maker, and were rejected.
The colors are typically opaque, though translucent strands do occur, especially in white examples.
