Top one looks like a swirl. None appear to be UV reactive from those pics (although UV reactive doesn't mean anything).

The "Ak" in Akro is pronounced the same as the "Ak" in Akron, Ohio.

If it helps - you can use the Ravenswood thread that I created long ago on MC.

As if Scott ever cared about marbles or marble collectors.

I'll note that these days I'm seeing a LOT of people putting UV light on everything thinking that its some kind of Magic ID proof of something - and mistaking 'REFLECTED' UV light for 'reactive' glass. Most don't want to be told that they are mistaken.

As noted - not oxblood. FYI - oxblood isn't transparent. Try not to "hope" for oxblood and it will be easier to accurately identify.

Scott Patrick had a well-known period of creating fake marble tournament medals.

Take care not to temperature shock that piece.

Left and center probably Jody Fine - but I should note that I'm not well-experienced in his work and he has produced over a long number of years and there is a lot of diversity in his work. I can't hazard a guess on the right - but the control shown is from an experienced artist (like Fine). Some day I hope to own one of Jody Fine slices of Marble Pie. I've never seen one for sale.

Not enough resolution, focus or closeness to the marble(s).

The photos are not focused enough, close enough or lit enough to judge.

A LOT of those were dug.

Simple MK BB DI.

Its an oddball, but I don't get Akro from it.

Its not a submarine. Thats the standard construction.

Jabo. Some people lack ethics.

Agree its not Akro, and I also get Japanese flavors from it.

The colors seem off. Maybe HDR or 'Vivid' setting on the camera is on.

It depends upon which corkscrews, and secondly their condition.

UV isn't a diagnostic.

Too blurred/out-of-focus to tell.

RBFs don't have characteristic annealing fractures.
