Featured Antique art glass paperweights identification

Hi Everyone,

I recently acquired these three pieces from an estate collection. Would anyone be able to help identify origin, period and maker? The only thing mentioned by the estate manager was that they were antique.

TIA,
Biju

 

For size

 

Can you get pulled back photos against a very plain background please? Including the base? I’m not immediately seeing antique.

 

I know very little about these but I do know beauty. Those are really lovely and a great find!

 

Here are some additional photos.
This one is 5 inches tall.

 

I know next to nothing about glass, but in my search for an inherited bottle, I came across this: https://www.worthpoint.com/worthopedia/st-clair-mike-mitchell-perfume-bottle-246899488

The Worthpoint bottle (ST CLAIR MIKE MITCHELL PERFUME BOTTLE 1971-74) is too young to be my bottle but it might relate to yours. Good luck!

 

Thank you, appreciate this lead - it might be by the same maker as mine.

 

My first thought on seeing the photos was circa 1970's St. Clair or Zimmerman production. Both manufacturers sold marked and unmarked weights. I am not familiar with Mike Mitchell's work but it makes sense stylistically.
