It's a beautiful blue, for sure! These are probably one of the hardest types to call Ravenswood vs Alley but FWIW, I'm about 52% Ravenswood to 48% Alley. lol
The first is likely a JABO Classic, probably 1992-2008 and the third is likely a Vitro Conqueror, probably from the mid 1940s.
Especially for the swirly ones!
If they're not glass, I'd guess polymer - pretty tough to get that sort of finish using clay. If polymer, they should feel quite a bit lighter than a glass marble of the same size.
