Here is a Regal Blue Sherbet stem made by the Fostoria Glass Company.
The pattern is Victorian 402. The bowl of the stem is a dark cobalt blue, Fostoria called this color Regal Blue.
This stem, in this color and shape, was made from 1933 - 1943. They measure 4" tall.
These are in near pristine condition with no chips, cracks, or nicks. There is no scratching and there is no visible wear. These obviously were well taken care of and handled with care.
They came from the estate of a woman in Southern Wisconsin
