I bet I can help you with a list. If you can give me your email I would be happy to send you a Word document I wrote that includes all the known marble making sessions at JABO, SMM, and DAS. There’s some more details in it too.
The fun hunt for euro sparklers is finding ones with both aventurine and oxblood in the same marble. They are out there, but not common at all and borderline hard to find/rare.
Oxblood on the interior looks the same as on the exterior. Easy to see in these examples. I have plenty of euro sparklers with what I think of as oxblood
Ok I definitely don’t want to even begin with this. Looking at the entire tray and I don’t see a single really good marble in the mix. The case is great but the marbles in it not so much. Lots of white based JABOs. If those are diamonds in the other tray…wow!
These ones show the amber ones better. In the run it shifts from almost clear transparent through amber to orange. It was a 5/8” run but there were peewees and oversized 3/4” marbles as part of the 5/8” run. The sizes were more variable than typically happens in a 5/8” run of classics for this color combo
