Just FYI, the pattern on Cairos is usually limited to one side of the marble and transparent striping is usually bubbly. Also, be sure to check out the "Mostly Pics" threads in Steph's Study Hall section of the forum for examples. ๐
DId you notice I edited my previous post to say that I think Cairo might be a better bet for that 3rd one? And yes, that wandering "puzzle piece" sort of pattern is not uncommon on Cairos or Heatons.
Things can look quite different for marbles with opaque striping and those with transparent striping glass, like the last one you showed. BTW, what size is that marble?
The only real Swirls Akro made were errors, although certain types like Carnelians and Ades can get a little swirly. This one's giving me a Heaton vibe.
