I tend to agree with the Chinese provenance, but having said that, I am beginning to think that we may have to stop thinking that Chinese glass is less desirable than Murano (as long as it is honestly labelled) because if you look at this piece it is clear-cased as well as having a two layer internal structure of both the brown and the white. The spiral is realistic and very nicely crafted.... It looks a lovely display piece in my opinion.
