Thank you both very much for looking and responding. There is very little wear to the bottom, just some barely discernable scratches along the ridge around the pontil indentation. While I was dubious about most of the spectacular description on the auction posting, I thought I was sure that it was a Murano piece. I have read most of the available material on fakes from Taiwan and China.
I wish I had something to contribute to discussions, but for now I will just have to tag along and pay attention. Thank you again.
