Actually, the quote you present is a statement made by Stefany. She can ably defend or amplify her point of view. I don't (or would not) say it's wrong.

However, my opinion is somewhat different. Since zi beads are largely found by Tibetans, or are acquired as ancient beads (not made for them). I would have to classify zi beads as amulets. They serve a general function, and/or have a list of attributes..., but they were not made for their owners to serve specific functions.

I think there ARE certain beads in Tibet that were made for specific functions, for the person who receives and uses them. These, I would say, are talismanic. I have documented one such bead from a private collection in the Eastern US.
