These are nice images William,
The small pink one is just a very nice marble—transitional—not Akro. Pink in any Marble is not common.
Transitional marbles will look like Akro corkscrews and visa-versa. This is because Akro Agate used so many variations in color, nothing to be ashamed of here, I thought that the first image was a very cool Akro Cork and they might just show up in this color combo—who knows?
The second one is a WVS gone wild imho, not an Akro. There were a few companies that made a nice egg-yolk color besides Akro.
Marble—On and keep asking for sure!!
