I highly recommend Paropamiso near Piazza San Marco—operated by my friends Michel and Nora. I sincerely believe it is the most beautiful bead store in the world. JDA.

P.S.—I am currently composing and posting photos from my recent trip to Venice and Murano, that includes the Glass Museum, Paropamiso, and the Moretti Company. This "cyber tour" is presented at my FaceBook Group, VENEZIA 2018.
