1950's Bryce 664 Amethyst Clear Diamond Stem (8) 6.25" x 2 1/8" wide at rim. I think these are small champagne flutes. This is an extremely uncommon pattern in which not every shape is documented. I'm 100% sure and guarantee them to be Bryce 664. Bryce went out of business in the 1960's. They're all perfect with no cracks, chips, cloudiness, restorations, or scratches.
