Lustrousstone,
Yes it is hollow, and has indeed been lined with silver.
Ross:
I can see what Your saying, but how do you think it is blue on the outside? Does yours have an embossed feel to it?
It really is nice, but im struggling to put a glass factory and designer to it and date?
So far then i think the general feeling is thats it Murano.
I would love to hear from more paperweight collectors on this one.
Regards.
