I blew up a few of your images and lightened them a tad.
I see some white bits floating around in the green—no AV.
In my experience, green glass in marbles of all makes will show some AV looking green bits once in awhile. It has something to do with the ingredients of the green glass recipe. It was not intended to be AV but it sure can look like it.
Nice marble—no ID from me.
Marble—On!!
