Not at all but😁---when you "backlight them all", transparent colored marbles can get quite interesting especially when you are running out of marbles to sort (it has been awhile for me). Marble—On!!

Good eye William, Vacor Sunsets come less filled, more filled and in-between filled just like the Master Marbles that they often get confused with. I can roll with Vacor on this one. All opinions are welcomed and appreciated. Marble--On!!

I agree with Steph and commit to Vitro on the top right one. The bottom right may have Oxblood but I would have to see better images to confirm that. As always, more opinions are welcomed. Marble—On!!

I am OK with calling the last two Akro. The one on the far right may light up under UV light. Nice group! Marble—On!!

Me too--agreed.

Or a "Transparent" with a lot of action🙃. Marble--On!!

The white based one might be a unicorn—Vacor Unicorn that is. Marble—On!!

Probably sold in "Imperial" packaging of some sort. From the Far East. Marble--On!!

It will help no doubt--Nice group! Put a name on these Vitros. More opinions are needed. Marble--On!!

I believe that the OP is a Vacor Stingray/Sky. They were produced in different shades of blue. Marble—On!!

That is a nice Vitro on the left. Exotic Conqueror? More opinions are needed. Marble--On!!

Akro Cornelians are and odd marble. In hand under direct light they will show no transparency, they appear to be opaque even though you may see some subsurface white just underneath the surface. If you backlight them they will show through and in many cases you can see internal structure. They are a semi opaque marble. I have never seen one with any purely transparent glass involved. I have one that I keep with my Cornelians that displays like a red “Flintie” when backlit—opalescent. If any transparent glass is displayed I would call the OP a well filled slag------ Just to add to the confusion, Cornelians were called “Bricks” by collectors in the early days of machine made collecting. The OP is not a Brick. Marble—On!!

Here is a 25mm (about 1”) Vacor Atmosphere for my Sunday’s best. I just love these little hard to find devils—this is a good one. The first set is in my light room and the second set is under overcast sunlight. Marble—On!!

That is a good question. I just lit up an original unopened Jabo bag with UV light and both orange and yellow glowers were inside. So, they were made close enough together to be packaged together. I guess that says something. It may have been years apart between runs but who knows? I also hit a Vitro bag (when they were a division of Jabo) with UV light and only orange glow emmited. Marble—On!!

Yes--nice coverage on that one. Marble--On!!

X3 nice marble. Marble--On!!

I am thinking that this one is a Jabo. They can fool the best of us and maybe it fooled me too. More opinions are always welcomed and appreciated. Marble--On!!

Here is a ¾” Jabo “Last Dance” Oxblood loaded marble from December 2008. Marble—On!!

Here is a ¾” marble from the “Last Dance” Jabo Tribute run from 12/16 2008. Do not ask me the name; I am lucky enough to know the run date. Love it— Marble—On!!

The OP is an odd one and I am a little surprised that MK was not mentioned, consider it done. More opinions are needed and welcomed. Marble—On!!

It is a very nice Vitro imho--names an desigations, I am not into--with a few exceptions---mostlly Akro. Marble--On!!

OK then, addicted you are! Keep them coming is all that I can say. We all love this stuff. Marble--On!!

I would eat it in a minute--or three over coals. I love the throwback it will spawn and grow many more. Fresh water fish--what a blessing!

There are many sellers that come here for ID's, what better place in my opinion. I buy online and welcome you as a seller that is trying to represent. WARNING!! Many sellers that come here become collectors☠️. I welcome you and your honesty--keep them coming! Marble--On!!
