Bohemian crystal perhaps? There's no etch mark on the bottom to help you figure out who made the glasses?
Check Ebay if you haven't already. I searched for "Bohemian crystal coloured glasses." There are some examples of sets and single pieces.
Also, you might find them on one of the china/crystal replacement sites.
Echoing what saab said:
I have some shaped beautiful and made of crystal - nobody wants them.
They only have a value if someone wants them, and the young people today don't seem to value it, including our own adult kids and those of our family and friends.
