Yours also has a bit of oven brick, which is way more common in Master than Akro and, to me, the bubbles don't look right for Akro either. But Art is right, Akro probably made a lot more 1" marbles than Master did so . . .?
There is one example in this group of dug MKs that Steph posted in the Study Hall in 2017.
And there are a few in this bag of Gladding era Vitros I have . . .
You decide. 🙂
This is certainly the sort of business that is going to require a significant amount of time and effort to build a reputation for honesty and reliability, since you really can't see the entire surface of the marble using the encasement system they appear to be offering. But who knows, maybe they can make it fly.
It's surprising that they haven't already posted here to announce the availability of their services.
BitDefender didn't have a problem with the link but I removed it from my earlier post anyway. As for free advertising - sunlight is usually a good disinfectant . . .
I have never heard of a marble grading service or seen a professionally graded and encased marble.
I just did a Google search and found the Marble Grading Company.
I had never seen it before. It's pretty interesting but I know nothing about the service or who is involved with it. It will be interesting to see what we can learn though.
Thanks for pointing it out.
I think they are all Vitro. The last two, in particular, look like they might be newer ones from the Anacortes location. The other looks a bit more like a weak All Red.
You make a good point Ron, I really should do a better job of explaining why I think a marble is what I think it is. When I look at this one, I see what appears to be an attempt to form four ribbons - you can see/imagine that possibility looking at the first pic. It looks like there should have been two distinct ribbons on each side of the seam - they would have been located at the top and bottom of what now appear to be wide equatorial patches. It seams to me they just bled out so bad that it filled the area between them. This sort of bleeding between ribbons is fairly common on Rainbos.
RE: the potential Red Raven . . . I don't think it is one, and if there are tinges of purple coming out of that brown striping I'd be thinking hard about a Heaton Fawn variant. And I would go Vacor on the white-based marble that is upper right in the first pic, and probably that blue one too. The white based Alley is a nice one - looks a bit like a Strawberry Shortcake variant to me.
It's definitely not an Angel of any sort but this is one of those very rare occasions when I am going to disagree with Ron and say that I think it could well be a Peltier Rainbo. I don't have Ron's experience with Akros that's for sure but I don't recall any with two equatorial ribbons of the same color. The thought of a Vitro Whitie did cross my mind, though I don't think it is one.
