Hi Peter
I have no reason to believe that Arques has ever used the Fleur-de-lis, but somehow I don't thik this item is Steuben either - so I jumped to the largest French glassmaker by default... call it blatant speculation.
The colour is clear and bright, not yellowish, and the sound is high and dull - so I think it is semicrystal.
And the design turns out to be quite discreet. I just spent 15 minutes looking around wondering where I put it... it just blended into the background and became invisible.
