Hi mjbette,
Your glass is Lovely! I'm sorry that I don't recognize the stems off hand. I'll have to check my few books. Will let you know if I find anything.
They look to be newer to me. (just my humble opinion) That is to say not antique. I say this because of the color and the stem design.
Following the
Contemporary lead I think would be a good place to start to look for ID'ing your glasses.
Hope this info is helpful.
Best Wishes,
Yan
Warmest Regards,
Yan
