I am far from an expert in Venetian beads, although I own quite a few and enjoy studying whatever literature I can find on their history.

I look to Joyce, Stefany, and Wayne for their extensive knowledge, especially with regards to older vs. post WW2 beads from Venice. And right now Floor has a lot of experience with the reproductions from China and Indonesia, which is probably the most important area of study with respect to Venetian beads, sad to say.
