I think the Cat's Eyes are foreign. And the big clear blue ones are just machine-made marbles (Clearies/Purees) - industrial, games, crafts, whatever. No real way to tell who made it and it really doesn't matter since they have little collectible value. A bunch of different colored ones can look nice together though.

Well, the orange base color looks about right. I think the green patch is unusual looking. Unfortunately, it's too out of focus for me to say much more.

Nice Alley Flame upper right.

Conquerors are some of the most common older Vitros you will find - Phantom Conquerors a little less so. The difference is between the two is whether or not the body is veneered with white glass over clear transparent (Conqueror) or has internal filaments like yours (Phantom Conqueror).

I think it's really more about the concentration of colorants in the glass and the way those colorants combine to produce different colors. And I do not think MK makes a true black, even today. AFAIK, only Christensen, Peltier, Akro and some old Alleys can show a true black. You can often tell that colors are not true black by looking closely at the edges of the striping where color thins out or mixes with the adjacent glass. But this too depends on the chemistry of the glass and whether or not the adjacent colors of glass are miscible. CAC is famous for using different colors of glass that do not mix together. It's why CACs usually have very nice crisp borders between adjacent colors and very little bleeding.

Alley or Ravenswood, IMO, and I am leaning Alley.

I definitely was not implying the OP marble is Master. I was just pointing you to examples of non-Akro eyelashes.

Nice Vitro Hybrid Cat's Eyes and more collectible than the single color ones, IMO.

I think most are JABO, and I agree the slaggy blue one deserves a better look, although I think it might be newer too - maybe Vacor?

I agree with Steph too.

I agree with RAR too - it looks like a bigger one.

I think Marble King - looks a bit like a blended Blue Boy, IMO.

@Fire1981 Nice mibs, Rick. I have always liked those transparent red ones.

A nice one too!

They're not uncommon on Masters either - check this thread . . .

I like the second one better, Joep. But to really do a good experiment, I think you would have to take the photos on the same background at about the same time of day (so the sun is hitting the marble in about the same spot) and with the marbles in the same position (so you capture the same view of the marble under each condition).

Hello Eric, Welcome aboard!

Pretty marble, Joe, I really like the nice brown colors - I think it's and Akro.

Lashes aren't only found on Akro, of course, but that's part of why I was thinking Akro too. The shape and pattern of the top patch and the seams remind me of the Uniques I have been studying lately too. But I have to admit I have not seen another Akro like it. On the other hand, I haven't seen a Marble King like it either.

I don't recognize these as being American made, Joep, but I am not sure I have ever seen a Coca Cola logo marble that was American made, at least not by an American marble manufacturer. Maybe somebody else has?

Marble King did not produce a true black color. What often appears black is really dark purple, and where that color thins out over white it definitely takes on a lighter purple color but not a purple like this one, IMO. It seems to me that the prominent colors on this marble are green and purple, and there is some blue too. I think those dark colored streaks up in and near the top patch are where these colors come together in various ways to make dark or light browns depending on their "concentrations" or "thickness". In other words, I don't think the purple you see is coming out of those dark streaks like what you might see on a MK.

I agree, it's got a pretty nice spin on it too.

I'm going against the grain and thinking Akro.

Pretty neat, it's a new one to me. It seems like the idea is to build a maze and then move a marble through it by tipping the box. I found a bit more information here.
