VTG/Modern???

[TheOhGee]

Hey all I got a couple more that are stumping the Google machine…. LOTs of suggestions but nothing concrete?  Looking for maker on the “cats eye”  and whether or not the blue one is glass or Quartz (cold to the touch but doesn’t seem heavier than any other marble I’ve ever held given its size.)  🤷🏽‍♂️

swirl—  1•11/32”
blue— 2•1/2”

any/all help would be greatly appreciated 🙏 

-Cheers
