Unknown Etched Cobalt Stemware

I picked these (four of them) up in Florida (I think) a few months ago – or at least at some point in between.  Perhaps New York.  There are great antique shops with lots of glass in upstate New York.

I digress.  I thought that these pretty blue stems, with needle etched circles would be easy to identify.  However I have not been able to find them and have had no luck on a Facebook Glass ID group to which I belong.

They have a gorgeous rich colour and an interesting beaded stem.

Look forward to someone knowing that they are.
