Well done. Very difficult marble to photograph. Can usually only hope for a hint of the fire to come through.
We have to remember that the ad writers of the time weren't always or maybe even usually the marble makers. So I don't hold them to "narrow, distinct strip".
I think what people called Ringers could sometimes come from true Aces. Or could be Moss Agates. Some of the corky mosses have a lot of clear in addition to a ribbon of white. So probably some things from both styles have been called Ringers.
My continuing working hypothesis is that quality control was tough with Aces and they probably didn't catch on well enough to justify continuing to make the effort over a long period.
