Goblets are shaped very much like New Martinsville Moondrops goblets and Viking's Prelude goblets. The design is similar to New Martinsvile's Radiance pattern but the only known stemware in this pattern is a cordial with a straight stem and bowl. Cobalt versions of this goblet are shown here: http://chataboutdg.com/gallery/details.php?image_id=19665
It has been suggested that this is a go with type pattern produced by New Martinsville for the Radiance pattern.
Color and shape are similar to New Martinsville goblets. New Martinsville Radiance has some similar characteristics but documentation for this identification has not been found. A 2006 Ebay auction seller lists it as Radiance in a listing which includes a decanter which is also not found in any New Martinsville documentation.
The stem on the left measures 4 7/16" high, 2 1/4" across top. It holds approximately 3 oz.
The vertical design is comprised of slanted slashes.
