I've been through the wringer trying to find an attribution to this one. The best US site I belong to is out of hunches also. This color does not even come close to matching up with US glass opaques from any manufacturer. Measures 9 3/4" diameter & 3" height without the stand. True Aqua Blue, glows so it has some UD in the formula so I'm turning here to see if it might be English? Thanks, Ken
