I have a 6 3/4" stem water glass or wine glass and on the bottom in the center has wminarc. What glass company would have that acronym? Thank you for your help in this request. Rob
yes, that is what it says rather than w it is lu. I was unable to bring out the word Luminarc with my camera. Thank you. Rob
Here is a picture of the wine glass. Found out it is Luminarc Diamant Wine Glass 6 3/4“ Tall Crystal Glass. Rob
