Hi mmarc77
I think it is quite common for the same sulphide element to be used by different glass factories. I could believe the floral plaque weight was Belgian, but not necessarily Val St Lambert - there were many glass factories making items along these lines. But the paperweight might also be from Alsace, or somewhere in France. The fleur-de-lis could indicate a French origin, but the design has been used in many national and local emblems across Europe over the years. So there is a bit of uncertainty, I fear!
