Vitro v. Akro

I'm gonna say Vitro; Vitro (even tho both seams curve, they are shorter?) and last Akro?

Based on the guidelines I showed in that one post I wrote, you would think that the left marble is Vitro, but it is an Akro. They don't always follow the seam rule but usually they do. The middle does look like Vitro, and the right one is for sure Akro. Good calls!

Of course I get the one that doesn't fit the norm! I was sooo sure of that one; not so much on the second one. What traits lead you to Akro? The base glass? Pattern of the patch? Because it isn't veneered?

The second one has a strange vibe like some japanese marbles give too, but I think it's a vitro anyway.
The first one, it's a combination of things... all the things you mentioned add up... along with familiarity with that marble from seeing it (ones like it) before in examples that have more typical akro seams.
