American Agate Or Prima

Would like to know what others think about this marble at 0.60" I see at least two concepts concerning these, and at times they are opposed to each other. One claims CA American Agates are more opaque and variable in the ribbons color tending to orange, and the other is that AA are cloudy translucent and opaque and more narrow in color range in the red. And v.v. for Primas. My examples fall out nicely into these groups, and I guess now I think the former is for CAC (more opaque), and the latter is for Prima (more cloudy).

I am leaning Pelt Prima on this example...thinking that Prima tends to be a bit more cloudy, a bit more translucent. In addition, I can easily see the glass being Pelt on this one, but don't ask me why.

But like I've said before, I'm not really sure what to think about these, and I have some examples, and since these were foundational marbles for each manufacturer, I really want to know. Don't you? Anyone want to discuss a few examples of these?

I'll post this as mib #1 for easier reference. I recognize I might be all backwards on this. Heck, maybe this is neither of them. Thanks! John

This one is 0.70" and I think, an American Agate. The nine is in white, and I include an under-exposed example that shows it differently. Here the colored ribbons is more variegated in color than the other type, and there is less transparent glass overlaying the opaque. What do you think about mib #2? John

The second one does not look like a Prima Agate, to me, being so opaque. The first one may be a Prima Agate, being translucent, but I couldn't say for sure. I am not as familiar with these types as I would like to be, having never seen them in person.

i originally believed the AAs were more transparent and the Primas more Opaque. Then I got six different 2 seam American Agates(I have seen 1 box of the 2 seam types) and them being more opaque I flipped to thinking The hand gathered AAs were the more opaque and the Primas the more transparent. Well I am now the proud owner of a box of American Agates supposedly all original but 2(from grandmas sock drawer) and they are almost transparent to near Opaque, I now do not know if I can tell the difference. I also have purchased a box of Prima Agates several years ago and believed them to be AAs. They were all mixed with my AAs and Primas and there was very little difference.

I'd go for the Primas being more translucent, too. I think there's a better picture that maybe Steph can find, going back to an older Prima thread . . . but here's one I have -- (photo I mean, not box!)

Are there any Cac boxes that are labeled prima agates, or is it just gropper? Perhaps gropper called them primas, Cac called them American agates but they are the same? Marble mania has several pics of Peltier marbles in gropper prima Agate boxes, though I am sure they may not be original to the boxes

This is really helpful discussion. Maybe we can start say that some specimens of AA we can ID...that the variegated orange and red on white are AA and very likely all those of this type in the right box like that are, in fact, AA too. I really feel strongly are distinctive and don't cross into that shared similarity that both types have when they become more translucent. Maybe those will remain either or for some time.

The left box really does mess me up if I look at it too long, and but the right box looks more uniform overall (might be an illusion from size similarity)...but I just can't find the two outliers. I'm going to look at that picture for a good while. Thanks everyone for an informative thread. I'm going to pull mine all out again and move them around. More examples to come.

That is very likely Mike, Then Arnold more than likely took what he learned to CAC Just to make things clear the marbles in the Prima box are probably a mix of both, and the marbles in the AA box do range from almost clear to almost opaque, and they are supposedly all original to the box except 2. If red was not one of my colorblind colors it may be possible they would look much more different to me than they do.

Seems like a coin toss, all this. Still, I'm crazy about these...don't much care they are more monochromatic, to some boring. I'll take them off your hands. This is my AA/Prima hog...bigger at 0.82" and a real fine mib IMHO. I don't expect anyone to chime in, but please do if so inclined. I've gone back and forth on this one...now thinking this is CA. Tomorrow, Pelt, etc, etc. Some resemblance to the left box, bottom left. We can call this #3 for the post (the boxes excepted). John
