I belong to another forum on (mostly vintage) costume jewelry. Someone posted this piece and everyone is stumped as to what it's made of and who might be the designer/artist.
The comments so far include comments that it's "probably made of Pyrex" and that it might have been made by a woman in California. The owner states that it is heavy glass and that there is liquid inside the glass that makes the blue colour shift as the beads are moved. (I'm quoting.)
Someone added that "people in the glass community are pretty tight" and someone there might know.
Any ideas?
Thanks,
Beth
