I am not saying there are no authentic ancient beads in China that passed into that land from the Middle East. It would be a great surprise if there were not such beads. Plus, I have seen them.

What I am saying is that SOME of the beads being sold (over the past five years, that I know of) as "ancient Chinese" are not that, and have not been in China for very long. And, groups of these beads are typical of the inventories of Afghan and Himalayan merchants. I am reasonably sure your fake seals are expected examples of this phenomenon.
