This is a rare set of 12 Steuben water goblets featuring handblown amethyst optic ribbed bowls and foot and the amazing contrasting turquoise "Celeste Blue" stem. These are documented pattern #6062 of Carder's line drawings.
Standing 7 1/2" tall, these would set a dramatic and one of a kind table using the beautiful combination of springlike colors. Please see some suggestions in the last image.
A complete Steuben service is also available in amethyst glass.
