I think it's curious that Boshan is placed in quotes—since the primary place of manufacture is at Boshan. Or, a few other centers of bead-manufacture receive their canes from Boshan.

The newer beads have canes that have fewer spirals around the center. Nevertheless, these canes do spiral (!) and are different from the Venetian canes that inspired them, that have complete concentric stripe layers.

I showed the only "new" Chinese millefiori beads I am aware of, about 10 years ago, that I believe were not made by exploiting old stocks of canes.
