The crystal in this goblet is wonderfully crystal clear and just sparkles! I am not familiar with Josair Crystal, the best I can tell is that it may have been made in Germany or Sweden. I identified the goblet and pattern on Replacements, Ltd, which sells this stem for $29.99. The pattern is called "Empire" and was produced from 1964 to 1988.
This is the champagne goblet. It stands 5-5/8" tall. The goblet has a cut line about 1/3 the way down from the top, below that are eight large looped panels. The stem has eight sides also and the foot has a star pattern.
The goblet is in excellent condition, NO CRACKS, CHIPS, SCRATCHES OR REPAIRS. The crystal rings like a bell! I have a total of seven of the champagne goblets for sale along with other stems in this pattern.
