Modernist table lamps

My parents bought these two lamps at a flea market in New York City in the eighties.
They are chrome and blue glass. They have no make or id stamp or number anywhere on them.
I love them because they are very unique and decorative.
Does anybody have an idea where they might come from and when they were made?
I have been researching, but have not been able to find anything similar.
Thanks!!
