Pretty group!

This is a big one . . .

Oh wow, that's really remarkable. I'd be interested to know what you used as a prompt.

It's a nice Vitro TriLite but not an Aquamarine. Aquamarines have more brown . . .

All I can say is . . . Scroooby-Rooooo!

It looks a bit more like a slag than a WV Swirl to me but it's hard to see many defining traits - if I had to guess, I'd say Akro.

I agree, but now @Fire1981 refers to "both melted" pontils so I am really confused . . .

It's all the "stretch marks" that made me lean away from Master but, of course, I could well be wrong . . .

@akroorka That's a dandy Alley, Art. Here's another . . .

Those are some nice ones Charlie but then I'm partial to brown too. Opaque WV swirls are often easier to associate with a particular company, and I enjoy figuring out how to tell them apart and sorting them as best I can. I just suppose that after 25 years or so of collecting them, I've come to accept the limits of my abilities in that regard. Nevertheless, I enjoy a looking at a good vintage marble, regardless of who made it. 🙂

@cheese Jumpin' Jimminy, man - no missing the bling on that one!

Don't get your hopes for a definitive ID of transparent WV Swirls up too high, Charlie. They are the simplest of marbles - the slags of the WV swirl producers, basically, and they are notoriously difficult to ID with high confidence. Sure, there are some like the one you posted above that are much more likely to be from one company than another, but Jackson and every other WV Swirl producer made boxcars full of transparent swirls and many of them simply cannot be reliably attributed to a particular company. This is why, unless they are a particular type that can be reliably attributed to a particular company, or there is something else special about them, they are not highly sought after by collectors. This is not to say that they aren't attractive - I have loads of them that I enjoy looking at but I rarely spend much time trying to figure out who made them because, in the end, they are what they are and who produced them has little or no effect on their collectible or monetary value. I should add, of course, this might just be me. lol

Super nice pattern on that one, Chad.

Hah, welcome aboard Ralph - I was just looking at your book last night! lol

Yeah, I know where the pontil is, I just can't see it well enough to tell if it's faceted or melted or what it even looks like, really.

I think it's an Imperial with some "cold" creases and a little damage at one of the cutoffs.

Looks like one of Jackson's to me.
