Topic: Reversible glass - Champagne flutes?

[Axus]

Being a collector of 19th and 18th century glass does not mean I would"nt be charmed by (I suppose) more modern glasses.
Standing on a hidden shelf in a second hand shop I spotted these three beauty's.

I suppose they are champagneflutes. Almost 12 Inches ( 30cm.) in height. The cuppa(s) made of blown twisted clear christal with a deep blue, almost purple glass ring in the middle.

Surely the blue ring reminds me of old Murano chandeleers I saw. But the glasses are not signed so I have my doubts.
However; Searches on the Internet could'nt give a clue about their origine, ore even if it are really champagneflutes ore a sort of tableware with other uses.

Who has any idea?

Thanks for any information.

These are by Boris Sipek who worked for many years in Holland (glass, furniture) until he returned to his native Prague some time in the late nineties where he took charge of restauration of the Prague fortress.
I think the flutes themselves have been blown in the Czech republic.
Congrats on a nice find.
