. Colored cut glass in most cases is so hard to distinguish between European and American glass. The two biggest cut class companies in Europe in the early 1900's were Baccarat and Val St. Lambert. Both The U.S. and Europe cut some of the some patterns on clear beautiful blanks. Also, Europe supplied many blanks to the U.S. as their blanks were perfect. Many American collectors have no problems having European cut glass in their American Brilliant Cut Glass collection.
My first instinct is American Sinclaire........But, the color is odd, Dorflinger did the odd colors thru the years and they did have cutters who had home shops. Could be from a cutter from Dorflinger thru a limited production not for a wide distribution. But then, there is a third theory. And I think it is my strongest suspicion. I tend to think it is Bohemian. We have had several over the years, that have thought to be American, but turned out to be European. We have two really good examples on our Ruby Lane site that you'd think were US depression era cut glass but are not.
The piece is about 6" tall and was bought in the U.S. which I stated above means nothing as thousands of pieces of European cut glass was shipped to the U.S.
We would love to have picture proof on the piece which I am assuming is going to be impossible. Thanks for working on the beautiful goblet.
