vintage bohemian crystal goblets wine or water glasses, rare white opalescent cut to clear glass

Lovely, very unusual vintage cut to clear crystal goblets - the color is a white opalescent with the clear glass beneath. I believe these are probably Czech or Bohemian glass, I don't know the pattern name or maker.

This is a set of four glasses 5 1/2" tall, all in excellent condition without chips or damage. These are the largest, nicest cut to clear glasses I've ever seen - and I love that opalescent color!
